A Helical Wave Guide II (Classic Reprint), Phillips Ralph S.

Excerpt from A Helical Wave Guide II In recent years a great deal of research has been done on an ultra-high frequency amplifier known as the traveling-wave It has been found that this tube possesses the desirable properties of high gain, broad bandwidth, and low noise level. The essential part of the tube is a helical transmission line which is designed to pass an electromagnetic wave with wave length along the guide, and hence phase velocity along the guide, smaller than that of the free-space wave by a factor of about thirteen. An electron beam with a ... więcej

The Electromagnetic Field Produced by a Helix (Classic Reprint), Phillips Ralph S.

Excerpt from The Electromagnetic Field Produced by a Helix The electromagnetic field is found for an infinitely-thin per fectly-connoting helix subject to a monochromatic excitation. It is first assumed that such a field would induce a sinusoidal current on the helix. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Linear Ordinary Differential Operators of the Second Order (Classic Reprint), Phillips Ralph S.

Excerpt from Linear Ordinary Differential Operators of the Second Order A precise meaning will be assigned to the operator (l) in section two for the case when q(x) is real valued, and this will later (section four) be extended to complex q(x). For real q(x) two situations arise depending on the function q(x). In the limit point case there is only one possible interpretation for L and that is independent of a/b L is self-adjoint with a real spectrum. In the limit circle case, L has a pure point Spectrum which lies in the upper half-plane for Im [cl/b] 0 ... więcej
