Nonlinear analysis of phase relationships in quasi-optical oscillator arrays
A dynamic theory of coupled oscillators is developed and applied to the class of loosely coupled quasi-optical oscillator arrays. This theory permits the calculation of stable, steady-state phaseExpand

A new phase-shifterless beam-scanning technique using arrays of coupled oscillators
A method for electronic beam scanning in linear arrays of antenna-coupled oscillators is introduced which eliminates the need for phase shifters. It is shown that a constant phase progression can beExpand

Distributed analog phase shifters with low insertion loss
This paper describes the design and fabrication of distributed analog phase-shifter circuits. The phase shifters consist of coplanar-waveguide (CPW) lines that are periodically loaded with varactorExpand

FDTD analysis of wave propagation in nonlinear absorbing and gain media
An explicit finite-difference time-domain (FDTD) scheme for wave propagation in certain kinds of nonlinear media such as saturable absorbers and gain layers in lasers is proposed here. This scheme isExpand
