In this study, we demonstrate near-field measurement of a spoof surface plasmon (SSP) on a corrugated metal disk with concentric annular corrugation. The SSP is excited at the center of the disk and is probed by a needle antenna on the corrugated sur

A surface-wave oscillator (SWO) is one of the promising terahertz-wave sources based on excitation of a surface wave using an electron beam. The surface wave is formed by a metal periodic structure, and the frequency is determined by the size paramet

Spoof plasmon is surface waves extended along corrugated surfaces and the terahertz equivalent of optical surface plasmon polaritons for metals. The spoof plasmon may be effectively excited by an electron beam. The beam is perturbed three-dimensional

We studied the operation of an oversized backward wave oscillator driven by an electron beam with energy less than 100 keV for terahertz radiation. Cylindrical slow wave structures (SWSs) with rectangular corrugations and annular electron beam are us
