Printed Circuit Dispersive Transmission Line

View page
US Patent:
50436821, Aug 27, 1991
Filed:
Mar 2, 1990
Appl. No.:
7/487323
Inventors:
Hiroyuki Ikezi - Rancho Santa Fe CA
John S. DeGrassie - Encinitas CA
Assignee:
The United States of America as represented by the United States
Department of Energy - Washington DC
International Classification:
H04B 304
US Classification:
333 20
Abstract:
A printed circuit dispersive transmission line structure is disclosed comprising an insulator, a ground plane formed on one surface of the insulator, a first transmission line formed on a second surface of the insulator, and a second transmission line also formed on the second surface of the insulator and of longer length than the first transmission line and periodically intersecting the first transmission line. In a preferred embodiment, the transmission line structure exhibits highly dispersive characteristics by designing the length of one of the transmission line between two adjacent periodic intersections to be longer than the other.

Method Of Judging Carrier Lifetime In Semiconductor Devices

View page
US Patent:
45648077, Jan 14, 1986
Filed:
Mar 27, 1984
Appl. No.:
6/593801
Inventors:
Hiroyuki Ikezi - San Diego CA
Richard L. Freeman - Del Mar CA
Assignee:
GA Technologies Inc. - San Diego CA
International Classification:
G01R 3126
US Classification:
324158D
Abstract:
A method for judging whether a group of semiconductor devices have sufficiently short carrier lifetimes to make them suitable for use in high speed electronic circuitry. A determination is made as to the satisfactory carrier lifetime for a pn junction in the devices. A capacitance value representative of the pn junction, when reverse biased, is also determined. The pn junction is placed in series with an inductor sized so that the resonant frequency of the inductor and the pn junction, when reversely biased, is substantially equal to the reciprocal of the carrier lifetime. An oscillating voltage is applied to the series combination of the junction and the inductor, the voltage having a fundamental frequency near but above the resonant frequency and an amplitude greater than a predetermined level which is in the range of 3-5 volts. Finally, the device under test is rejected should an output taken across the pn junction show a substantial frequency component below the fundamental frequency.

Solid State Cyclotron Laser

View page
US Patent:
47232501, Feb 2, 1988
Filed:
Dec 20, 1985
Appl. No.:
6/811644
Inventors:
Tihiro Ohkawa - La Jolla CA
Hiroyuki Ikezi - Rancho Santa Fe CA
Assignee:
GA Technologies Inc. - San Diego CA
International Classification:
H01S 300
H01S 319
H01L 3300
H01L 2722
US Classification:
372 37
Abstract:
A solid state cyclotron laser device generate coherent electromagnetic radiation. A semiconductor configuration comprises an emitter region and a collector region separated by a base region and barrier layers on each side of the base. The semiconductor configuration is biased such that electrons enter the base region from the emitter region as hot electrons. A magnetic field applied by an external source to the base region causes the hot electrons to gyrate and quantize into Landau levels. An optical resonance cavity produces standing wave modes which stimulate the electrons to move from higher to lower Landau levels to generate conherent radiation. Electrons with decreased energy are removed at the collector in order to maintain the population inversion. The device is tunable by adjusting the magnetic field.

Soliton Pulse Compressor

View page
US Patent:
50669281, Nov 19, 1991
Filed:
May 2, 1990
Appl. No.:
7/517941
Inventors:
Hiroyuki Ikezi - Rancho Santa Fe CA
John S. deGrassie - Encinitas CA
Assignee:
General Atomics - San Diego CA
International Classification:
H03K 504
US Classification:
333 20
Abstract:
A pulse compressor for solitons includes a continuous dispersive non-linear propagation structure so constructed so that the wavefront of an individual soliton pulse is steepened. In addition, the pulse compressor has a continuously reduced time constant on a spatial, as opposed to a temporal basis. Various structures of the pulse compressor are described.

Monolithic Dielectric Microwave Window With Distributed Cooling

View page
US Patent:
59173890, Jun 29, 1999
Filed:
Jul 16, 1997
Appl. No.:
8/895323
Inventors:
Charles Porter Moeller - Del Mar CA
Hiroyuki Ikezi - Rancho Santa Fe CA
Assignee:
General Atomics - San Diego CA
International Classification:
H01P 108
US Classification:
333252
Abstract:
A microwave window is made as a flat layer of dielectric material having opposite first and second surfaces. Between these surfaces, the window is formed with a plurality of parallel coolant channels which, in cross-section, have racetrack configurations with flat sides and curved ends. The channels are distanced from each other in the window to establish parallel plate waveguides between the flat sides of adjacent channels. A plurality of cylindrical lenses are formed on the first surface of the dielectric layer to focus incident microwaves into convergence in a respective waveguide. Additionally, a plurality of cylindrical lenses are formed on the second surface of the dielectric layer to refocus microwaves emerging from the parallel plate waveguides back into a substantially parallel relationship as the microwaves radiate from the window.

Transmission Line Microwave Generator

View page
US Patent:
47194294, Jan 12, 1988
Filed:
Apr 14, 1986
Appl. No.:
6/851977
Inventors:
Hiroyuki Ikezi - Rancho Santa Fe CA
Torkil H. Jensen - Del Mar CA
Assignee:
GA Technologies Inc. - San Diego CA
International Classification:
H03K 301
H03K 353
H03K 386
US Classification:
328 65
Abstract:
The present invention is a device for generating high power microwave pulses using a nonlinear dispersive transmission line connected by a switch means to a source cable means and a high voltage source. The closing of the switch means sends an electrical pulse propagating from the source cable means through the transmission line. The pulse decomposes into a short, high power pulse of microwaves which consists of an array of solitons. The output of the line may be coupled into an antenna, wave guide or other load.

Multiple Pulse Generator Using Saturable Inductor

View page
US Patent:
51189690, Jun 2, 1992
Filed:
Feb 9, 1990
Appl. No.:
7/478106
Inventors:
Hiroyuki Ikezi - Rancho Santa Fe CA
John S. deGrassie - Encinitas CA
Assignee:
General Atomics - San Diego CA
International Classification:
G11C 1302
H02J 310
US Classification:
307419
Abstract:
A high power multiple pulse generator includes a plurality of transmission line sections, adjacent sections of which are coupled together by a saturable inductor. One transmission line section is switchably connected to a load impedance through an output switch. With the output switch open, the coupled transmission line sections are charged to a desired voltage potential. A burst of multiple pulses is generated by closing the output switch, causing the charge on the transmission line section connected to the load through the closed switch to be delivered to the load as a first pulse. This first pulse has an amplitude equal to one half of the charging potential and a duration that is a function of the length of the transmission line section. Once this first pulse is delivered to the load, a voltage is developed across the saturable inductor coupling the discharged transmission line section with an adjacent charged transmission line section, causing current to flow therethrough. When the current flowing through the inductor reaches a certain amplitude, the saturable inductor saturates, effectively transferring the charge of the next transmission line section to the load as a second pulse.
