Transmission coefficient for a semi-classical wavepacket

Physics Letters A, 1981
Abstract The semiclassical WKB wavepacket formalism, already introduced to treat non-radiative processes in multidimensional space, has been improved by the evaluation of normalization constants which enter the transition rate. A comparison is made between the wavepacket and the transmission-coefficient methods.

Microwave transmission coefficient of the heterogeneous media

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
Possibility of the theoretical description of the interaction of the microwave radiation with heterogeneous media is considered in report on example of the dry sandstone. The results of the experimental studies of spectral dependency transmission coefficient within the range of 150-600 GHz are discussed.

Transmission coefficient correction for DACs

IEEE Design & Test of Computers, 1996
Many digital-to-analog converters achieved as integrated circuits by CMOS and bipolar technologies have a transmission coefficient error, often called full scale error. The article presents circuits to correct for such error in DACs with resistive ladder network R/2R and separate resistor, r.

Reflection and Transmission Coefficients for a Diffused Interface

Applied Optics, 1968
The reflection and transmission coefficients for an inhomogeneous layer separating two semiinfinite homogeneous media are examined. Two different cases are investigated, each with a different permittivity profile for the inhomogeneous layer. Detailed examination of these coefficients reveals the relation of their magnitude and phase to the wavelength ...

Transmission coefficient of a fractal layer

Physical Review A, 1991
A wave passing through a one-dimensional fractal layer described by the Weierstrass function is studied within a framework of a perturbation method. It is shown that a transmission coefficient in a region of sufficiently small wavelengths consists of two components. The first corresponds to boundary scattering and describes resonance effects.

Transmission coefficient of a grid electrode

Fluid Dynamics, 1974
The behavior of conducting emulsion drops (carrying a constant charge) in the region between electrodes connected to dc sources is studied. Assuming that the concentration of the dispersed phase is reasonably low, the problem may be reduced to one of determining the motion of an isolated drop close to the electrode.

The transmission coefficients of a random system

Applied Scientific Research, 1981
We study the reflection and transmission coefficients of a strip of parallel chains with random masses. We show that the transmission coefficients decay exponentially. For this we need the applicability of a theorem by Tutubalin, which is formulated as a conjecture.

A Coefficient Model for a Hydrostatic Transmission

Transactions of the ASAE, 1983
ABSTRACT AMATHEMATICAL model for calculating the steady state performance of a hydrostatic transmission was developed and evaluated with experimental data. Evaluation of the model led to revision of the model equations for improved accuracy. The final model was evaluated for both full and partial displacement operation of the transmission with good ...
