Patent number: 9306371Abstract: 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.Type: GrantFiled: April 20, 2012Date of Patent: April 5, 2016Assignee: BAE Systems Information and Electronic Systems Intergration Inc.Inventors: Yannick C Morel, John E McGeehan, Clint J Novotny, Simon Y London

Patent number: 8373518Abstract: Conductive segments (transmission line conductors) are positioned within a transmission line structure in order to generate multi-cycle microwave pulses. The conductor segments are switchably coupled to one or the other conductor of the transmission lines, inside the transmission line structure. Microwave pulses may be induced in the transmission line by closing the switches in a controlled manner to discharge successive segments, or successive groups of segments, into the transmission lines. The induced pulses travel uninterrupted along the transmission lines in a desired direction to the load. Efficiency of systems and energy delivered to the load in multi-section transmission lines is increased and/or maximized by adjusting the ratio of characteristic impedances associated with the transmission line conductor segments according to an optimum ratio.Type: GrantFiled: June 14, 2011Date of Patent: February 12, 2013Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventor: Simon Y.

Patent number: 8207634Abstract: A compact multi-cycle high power microwave generator and a method of using the generator to generate microwave signals is disclosed and claimed. The apparatus includes one or more charged transmission line sections. Each transmission line section includes a first conductor that is section-specific and a second conductor that is common to all of the sections. A switch is associated with each section, each switch being operatively connected to a respective one of the first conductors. The apparatus includes third, common conductor that is not charged and that is operatively connected to each of the first conductors through its respective switch. The apparatus further includes a load, with the second conductor, the third conductor, and the load being operatively connected. Thus, the number of section-specific conductors, the number of charged transmission line sections, and the number of switches are all equal. Engagement of the switches generates a multi-cycle microwave pulse.Type: GrantFiled: February 1, 2010Date of Patent: June 26, 2012Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventor: Simon Y.
