International Classification:

H01S 4/00

US Classification:

333 20

Abstract:

A Multi-Cycle Digital High Power Microwave (MCD-HPM) source includes a microwave transmission line (MTL) to which a plurality electrically charged thin film transmission lines (TFTL's) are connected by switches. The switches are activated in sequence to generate a square wave at a microwave output frequency. The activation signal is controlled by a free space time delay, which can vary the timing and/or routing of the activation signal by modifying at least one free space element, thereby adjusting the switch activation timing and varying the output frequency. In embodiments, the switches are photo-conducting switches, the activation signal is a laser beam, and the switch timing is varied by reorienting and/or repositioning mirrors and/or other elements in the free space time delay. The elements can be manually adjusted, or mounted on motorized stages and automatically controlled. Optical amplifiers can be included to compensate for losses in the time delay elements.

International Classification:

H01F 1/22
C08K 3/34

Abstract:

The present disclosure relates to polymer composites that include a thermoplastic polymer, network structure and a soft, ferromagnetic particulate material. The polymer composites may be used, for example, as magnetic flux field directional materials. The present invention also relates to methods of making the polymer composites, e.g. polymer composite sheets, of the present disclosure. In one embodiment, the present disclosure provides a polymer composite including a thermoplastic polymer, network structure; and a soft, ferromagnetic particulate material distributed within the thermoplastic polymer, network structure. The weight fraction of soft, ferromagnetic particulate material may be between 0.80 and 0.98, based on the total weight of the polymer composite and/or the thermoplastic polymer may have a number average molecular weight between 5×10g/mol to 5×10g/mol.

Abstract:

A microwave module is described. The microwave module includes a base bracket, a window plate and a lid. The base bracket is configured to contain a photoconductive switch, a radio-frequency transformer and dielectric oil. The window plate, which is transparent to optical light, covers a first portion of the base bracket in which the photoconductive switch is located. The window plate is sealed to the base bracket. The lid, which includes a cutout to allow the radio-frequency transformer to pass through the lid, covers a second portion of the base bracket in which the radio-frequency transformer is located. The window plate is sealed to the base bracket, and the lid is sealed to the window plate, the base bracket and the radio-frequency transformer to contain the dielectric oil within the microwave module.
