A coupled mode description of the backward–wave oscillator and the Kompfner dip condition
1955 Edition, Volume 2, October 1, 1955 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The start oscillation condition for the backward-wave oscillator and the operation of the traveling-wave tube amplifier at the Kompfner dip point are described from the point of view...

Coupled-Mode Description of Crossed-Field Interaction
1961 Edition, Volume 9, March 1, 1961 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The coupled-mode theory is developed for two-dimensional M-type flow, and a system of five coupled-mode equations is obtained. A fifth degree secular equation is found for the perturbed propagation constants of the...

Coupled-mode description of a nonuniform transmission line
1968 Edition, Volume 56, July 1, 1968 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Coupled-mode analysis provides a conceptually simple technique for the analysis of nonuniform transmission lines and nonuniform coupled systems. The variable series and shunt elements couple backward and forward...

Coupled-mode description of space-charge waves on nonuniform beams
1965 Edition, Volume 12, October 1, 1965 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Coupled-mode theory is employed to describe space-charge wave propagation on an electron beam drifting in a non-uniform region. The nonuniformity may arise in several ways. These include a potential variation, a beam-radius variation, or a...

A Coupled Mode Description of Beam-Type Amplifiers
1955 Edition, Volume 43, February 1, 1955 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A description of beam-type amplifiers, in particular the klystron and traveling-wave tube, is developed in which the electroh stream and the circuit are treated as coupled transmission lines. The method allows the...

A Coupled-Mode Description of the Reggia-Spencer Phase Shifter
1966 Edition, Volume 66, January 1, 1966 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Although Reggia-Spencer phase shifters have been built for many years, no completely satisfactory description of the principle of operation of this type of device has appeared in the literature. Of the many theories advanced to explain...

A composite-resonator mode description of coupled lasers
1986 Edition, Volume 22, August 1, 1986 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We investigated the behavior of two lasers operating with coupled resonators. Our analysis involves a decomposition of the laser field in terms of the passive composite resonator eigenmodes. The interaction between the laser...

A Realistic Description of Mode Propagation in Suspended Coupled Stripline
1985 Edition, September 1, 1985 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The effect of finite metallization thickness and mounting grooves on the propagation characteristics of suspended coupled striplines is investigated with a rigorous and versatile hybrid mode analysis. Presented results demonstrate that...

Buildup of oscillations in crossed-field backward-wave oscillators
1972 Edition, Volume 19, November 1, 1972 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Coupled-mode description of the interaction process in crossed-field backward-wave oscillators is used to derive the oscillation condition and the spatial variation of wave amplitudes during buildup...

On the application of coupled mode theory for modeling fiber Bragg gratings
2000 Edition, Volume 18, February 1, 2000 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We remove some ambiguities associated with the coupled mode description of light propagation in fiber Bragg gratings (FBC's). We show, in particular, that different methods employed in the literature lead to physically distinct results. The...
