Book Description
Cyclotron resonance interaction between a electron beam and a circuit wave to produce backward wave oscillation in an unloaded waveguide in the S-band was investigated, and the development of a prototype oscillator tube to work in the 6-4.5 mm range was also completed. This prototype tube was so constructed that it could be placed in a narrow air gap of an iron-core electr magnet which provided the necessary field for electron cyclotron motion. However, it did not have the desired performance. Modifications made on the prototype tube and tube performance after modification are described. A different design is also reported. The main difficulty encountered in improving tube performance was the inability to control electron injection properly. Even at the conclusion o the experimental work described here, the control was not entirely satisfactory, though net electronic gain from the tube was obtainable. A secondary difficulty was the lack of space in which to place the tube components; however, this was later solved. (Author).

Book Description
Infrared and Millimeter Waves, Volume 8: Electromagnetic Waves in Matter, Part I compiles the work of several authors while focusing on certain aspects of infrared and millimeter waves, such as sources of radiation, instrumentation, and millimeter systems. This volume discusses electromagnetic waves in matter. The first chapter covers the properties of the dielectric materials, which is then followed by a discussion of far-infrared spectroscopy on high polymers. Chapter 3 tackles submillimeter solid-state physics, and Chapter 4 reviews the theory of infrared and far-infrared free-carrier behavior in semiconductors. The improvements in pyroelectric detectors are then reviewed. The sixth chapter discusses cyclotron and Zeeman transitions in photoexcited semiconductors at far infrared, while the seventh chapter discusses high temperature infrared reflectivity spectroscopy. Chapter 8 covers millimeter and submillimeter waves' interaction with giant atoms. The last chapter is about spectroscopy of InAs-GaSb layered structures. This book will be of great use to researchers or professionals whose work involves infrared and millimeter waves.

Book Description
The operation of the induced resonance electron cyclotron (IREC) maser at Doppler upshifted cyclotron harmonics is studied. A set of fast-time averaged nonlinear equations of motion is derived for the particle motion near an arbitrary harmonic at any index of refraction. The small signal efficiency is computed analytically and the minimum current to start the cavity oscillations is obtained. The nonlinear equations of motion are integrated numerically. The interaction efficiency at the first few harmonics is found comparable to the efficiency at the fundamental. The sensitivity of the efficiency to the beam thermal spreads is minimized by the proper selection of the index of refraction. Keywords: Masers; Gyrotrons; Radiation sources; Millimeter wavelengths; Wave particle interaction.
