We have been exploring several slow-wave circuits for terahertz frequency backward-oscillators that are suitable for microfabrication. The circuits include folded waveguide circuits based on either rectangular or photonic crystal waveguides, as well

Experimental investigations of the substrate deposition temperature and annealing temperature influence on aluminum films deposited on diamond substrates were conducted. Tests were performed at direct current and at 101.55 GHz. Minimum resistivity le

A method is shown to accelerate the convergence of a partial series. It is based on a generalized form of Kummer's comparison method in which a set of functions with unique properties are fitted to the summand values. This process subtracts off the t

The theory developed by M. Chodorow and E.L. Chu (Stanford Univ. Tech. Rep. TR249, 1954) is expanded to include the problem of a contrawound helix interposed between two dielectric regions, symmetrically oriented inside a conducting cylinder. The sin

We are developing backward wave oscillators (BWOs) for use above 1 THz. The devices employ photonic crystal waveguide (PCW) circuits for the slow-wave circuits, micromachined into silicon substrates and coated with gold to form the metallic photonic

The authors describe an effort to develop O-type backward-wave oscillators for the frequency range from 600-1800 GHz for local oscillators in spectroscopy measurements in space applications. Recent interdigital O-type backward-wave oscillators have y

The need to eliminate the backward traveling wave in HARP (harmonic auto-resonant peniotron) interactions is demonstrated. The theory and design of a ring-type resonant cavity to achieve this are described. It is shown that this cavity can support hi

A type of mode analyzer based on an array of field probes at the surface of an overmoded circular waveguide is described. This type of device is needed in high-power microwave research where waveguide sizes typically permit dozens of modes to propaga

Recent research at the University of Utah on U.S. Army Research Laboratory Contract No. DAAL01-95-K-3541, provided the design and construction of two backward wave oscillators: (1) a tunable oscillator from 300-600 GHz, and (2) a tunable oscillator f
