A SIDE FROM HELICES, the circuits most commonly used in travelingwave tubes are iterated or filter-type circuits, composed of linear arrays of coupled resonant slots or cavities.
N CHAPTER VI we have expressed the properties of a circuit in terms of its normal modes of propagation rather than its physical dimensions.
In travelling wave distributed photodetectors, half the photocurrent generated in each individual photodiode is lost in the input termination.
Optical isolators, which allow light to pass in one direction but block light in the opposite direction, are one essential element in a laser or an optical amplifier system to protect the system fr
Two medium power travelling-wave tubes to give power outputs of 8 W and 12 W respectively at frequencies around 6Gc/s are described.
A single molecule break junction device serves as a tunable model system for probing the many body Kondo state.
In this article we describe a very simple means of treating microscopic fluctuations in noise theory.
We prove that tree isomorphism is not expressible in the language ( FO + TC + COUNT).
We study relations on trees defined by first-order constraints over a vocabulary that includes the tree extension relation T
In this paper, we provide the first systematic study of subscription aggregation where subscriptions are specific with tree patterns (an important subclass of XPath expressions).
