Method And Apparatus For Digital Synthesis Of Long Multi-Cycle Microwave Pulses

An apparatus for generating a plurality of electrical pulses on a transmission line, comprising:

• at least two transmission line conductors at a distance D, having characteristic impedance Z;
• a plurality of conductive segments interposed between and electrically isolated from the two transmission line conductors, wherein the segments are capable of being charged and discharged to create a microwave pulse train on the transmission line conductors, and
• wherein the segments are positioned a distance D1 from a corresponding one of the transmission line conductors, D1+D2=D, and a ratio of D2/D1 is chosen to be near optimum for efficiency and energy transfer, and odd numbered segments are switchably coupled to and positioned at distance D1 from one of the transmission line conductors and even numbered segments are switchably coupled to and positioned at a distance D1 from the other one of the transmission line conductors.

A method of generating microwave signals in a multi-section transmission line, comprising:

• first switching to discharge at least one first segment into transmission line conductors;
• second switching to discharge, after a period of delay, at least one second segment into the transmission line conductors to create a bipolar pulse,
• wherein the transmission line conductors are positioned a distance D apart and the first and second segments are positioned within the transmission line conductors, and further wherein the first and second segments are positioned a distance D1 from a corresponding one of the transmission line conductors, D1+D2=D, and a ratio of D2/D1 is chosen to be near optimum for efficiency and energy transfer.
