The duty-cycle randomness (DCR) of the Bragg grating of the distributed feedback (DFB) lasers introduced by the fabrication process is inevitable, even with state-of-the-art technologies such as electron beam lithography and dry or wet etching.This w

Multistage depressed collectors (MDCs) of traveling-wave tubes (TWTs) are used to collect kinetic power of a spent electron beam, recover part of this power to a useful electric power, and, by such a way, enhance the overall efficiency of TWTs. The h
