The mode-selective microwave reflector with periodic rectangular corrugations in the inner surface of a circular metallic waveguide is studied in this paper. The relations between the bandwidth and reflection coefficient for different numbers of corrugation sections were studied through a global optimization method. Two types of reflectors were investigated. One does not consider the phase response and the other does. Both types of broadband reflectors operating at W-band were machined and measured to verify the numerical simulations.

“…In the millimeter and sub-millimeter wavelength community, RF sources with compact configuration, high efficiency, and high output power have many potential applications, including satellite communications, radars, molecular spectroscopy, bioimaging, and plasma science [1][2][3][4][5][6][7][8][9][10][11]. The extended interaction oscillator (EIO) has been widely studied as a promising source to satisfy some of these applications, due to its high radiation power and compact configuration [1][2].…”

AbstractA preliminary design of a G-band extended interaction oscillator (EIO) driven by a sheet electron beam is presented in this paper. PIC-3D simulations reveal that an output power of about 3.1 kW can be achieved when driven by a sheet electron beam with a voltage of 31.5 kV and a current of 0.85 A. The oscillation frequency is 197.3 GHz and the electronic efficiency is about 11.6%.
