We study the possibility of analog signal processing for the upcoming terahertz (THz) high-
bitrate communications using as an example the problem of dispersion compensation in the …

A wide variety of desirable antenna beam patterns can be synthesized by optimal excitation
and phasing of the HE 11 and HE 12 modes in scalar corrugated feedhorns. However, the …

An output coupler for a W-band high power wideband gyroamplifier has been designed,
manufactured, and experimentally measured. It consists of a high performance sin 2-parallel …

Gyrotrons produce power in high-order, transverse electric modes that are typically
converted to a Gaussian beam inside the tube. In fusion plasma heating applications, the …

Circular corrugated waveguides are often used in fusion applications at single, multiple, or
broadband millimeter frequencies due to their low ohmic loss, expected large frequency …

As an initial step toward exciting optical vortices using high-power millimeter waves, this
study developed a method for inducing vortex modes within a cylindrical waveguide using …

Two miter bends are described for monitoring the power transmitted in an oversized
corrugated wave-guide. One has an array of holes in its mirror that couples a small fraction …

A new frequency-stepped Doppler backscattering (DBS) system has been integrated with a
real-time steerable electron cyclotron heating launcher to probe local background …

A new code framework, MORAMC, is presented which model transmission line (TL) systems
consisting of overmoded circular waveguide and other components including miter bends …

The development of resonant diplexers for millimeter waves can improve the flexibility,
simplify the system complexity, and extend the performance of electron cyclotron resonance …
