Theory of the microwave crystal mixer

Proceedings of the IEE - Part B: Radio and Electronic Engineering, 1958
The rectifier which has an exponential characteristic and parasitic resistance and reactance is considered. By making certain reasonable approximations a simple expression giving the condition for optimum conversion loss is obtained, and from this a set of universal curves, showing optimum conversion loss as a function of the basic contact parameters ...

Theory of the scintillation fading of microwaves

IRE Transactions on Antennas and Propagation, 1957
A theory is presented indicating that the scintillation fading may be attributed to the incoherent scattering of microwaves by atmospheric irregularities in mass motion at an average velocity. By use of the perturbation theory, the resultant of scattered fields at the receiver is calculated which, on account of the interference with the direct wave ...

Microwave transmission: theory and practice

1998
In this chapter we first consider basic concepts of microwave power transmission, introducing the essential parameters commonly used, familiarity with which is vital to a proper understanding of the technology. Transmission in coaxial, parallel-plate and open-wire lines in the elementary transverse electromagnetic (TEM) mode is then discussed, before ...

Microwave Radiations: Theory and Instrumentation

2015
This chapter deals with the theory and instrumentation of the application of microwave to chemical syntheses. Starting from a generalized introduction to the electromagnetic spectrum, details about the specific microwave thermal and non-thermal effects, hazards, safety measures and limitations of reactors are discussed.
