Applications of high-power Terahertz (THz) sources require low-loss transmission lines to
minimize loss, prevent overheating and preserve the purity of the transmission mode …

Although orbital angular momentum (OAM) millimeter-wave wireless communications have
attracted much attention given their potential to provide an additional degree of freedom in …

Abstract The European Union is working toward providing 2-MW, coaxial-cavity, continuous-

With a view to using Phase Retrieval to accurately predict Terahertz antenna far-field from
near-field intensity measurements, this paper reports on three fundamental advances that …

An instantaneous measurement system of high-power millimeter-wave was proposed and
demonstrated with a 28 GHz gyrotron at the Plasma Research Center, University of …

A semiquantitative technique for imaging of high-power millimeter wave (MMW) beam using
visible light from the plasma of an MMW-induced gas breakdown, which was initiated by a …

We present a high-sensitivity technique for time-resolved imaging of millimeter waves
(MMWs) using the visible continuum (VC) from the positive column (PC) of a medium …

Electron cyclotron (EC) heating and current drive is a well-established auxiliary heating
mechanism for tokamak plasmas, which is also effective in assisting plasma breakdown and …

In this paper, we describe the development and design procedure of the new kind of coaxial
TEm, 1 modes generator based on ring resonator with coupling apertures. The generator …

This work focuses on the accuracy of the mode content measurements in an overmoded
corrugated waveguide using measured radiated field patterns. Experimental results were …
