The authors present a survey of modern nonlinear CAD (computer-aided design) techniques
as applied to the specific field of microwave circuits. A number of fundamental aspects of the …

Basic principles of heterodyne techniques are introduced and the various components of a
heterodyne system are summarized. Special applications in ECE, interferometry and …

Terahertz waves, which lie in the frequency range of 0.1-10 THz, have long been
investigated in a few limited fields, such as astronomy, because of a lack of devices for their …

A complete quantum generalization of microwave mixer theory is constructed for nonlinear
single-particle tunnel junctions. The result represents a unification of the concepts used to …

Radio-frequency (RF) circuits exhibit several distinguishing characteristics that make them
difficult to simulate using traditional SPICE transient analysis. The various extensions to the …

The recent shift in focus from defense and government work to commercial wireless efforts
has caused the job of the typical microwave engineer to change dramatically. The modern …

Covering a broad range of topics-from generation, propagation and transmission, to
components, circuits, antennas, and millimeter wave applications and systems-this work …

A method has been devised to experimentally characterize a packaged GaAs Schottky
barrier diode by inserting it into a microstrip test mount. The nonlinear equivalent circuit …

The operation of GaAs Schottky barrier diodes, the critical mixer element used in heterodyne
receivers for a variety of scientific applications in the terahertz frequency range, is reviewed …

The operation of semiconductor devices is based on charge transport, ie on the motion of
free carriers in the conduction and valence bands. Under the effect of applied external forces …
