Frequency self‐stabilization of the diffraction radiation oscillator in a biharmonic mode

AbstractThis paper treats the experimentally observed operating features of the diffraction radiation oscillator in a situation of maintaining biharmonic oscillations in the resonant circuit. The process of electron‐beam interaction with biharmonic oscillation is shown to realize intrinsic physical mechanisms of the oscillator frequency stabilization which are put into effect depending on the dispersion competition of the waves in the oscillator resonant cavity. © 2001 John Wiley & Sons, Inc.

THEORETICAL ANALYSIS OF THE TWO-TERMINAL MOS CAPACITOR ON SOI SUBSTRATE

The present paper deals with the analytical and numerical study of MOS capacitors on SOI substrates. The major concern is the theoretical treatment of such devices with floating substrate. Special care has been taken to keep the mathematical modeling consistent with physical considerations. The importance and the role of the underlying silicon substrate have been highlighted. The different operating conditions of the capacitance-voltage characteristic have been interpreted in terms of device intrinsic physical mechanisms.
