Statistical law of surface impedance distribution
IGARSS '96. 1996 International Geoscience and Remote Sensing Symposium, 2002Theoretical equations are developed to describe the EM induction exploration of subsurface layered structure. The theory is applicable to LF, VLF and ELF sounding of crustal rocks.

Distribution of current, surface impedance, and damping in superconductor coupled microstriplines
Technical Physics, 1997The nonuniform current distribution in the transverse cross section of the coupled conductors of a microstripline made with superconductor films leads to a substantial dependence of the losses in the line on the relative position of the coupled strips.

Research of mutual radiation impedance effect on surface vibration velocity distribution
2017 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2017Based on the lumped parameter theory of piezoelectric transducer, the mathematical relationship between mutual radiation impedance and surface vibration velocity distribution of the array element is established, and then the simulation experiments were carried out for a 5×5 planar array.

IEEE Transactions on Antennas and Propagation, 1995
The input impedance of a thin (a/spl Lt//spl lambda/) center-fed dipole with an assumed sinusoidal surface current distribution is obtained by the Poynting vector method. It is shown that by retaining the surface current distribution rather than replacing it by the classical equivalent line current on the dipole axis, the Poynting vector method can be ...

2018 Days on Diffraction (DD), 2018
Electrodynamic characteristics of a strip loop antenna located on the surface of a gyromagnetic cylinder are studied using the integral equation method. The cylinder is aligned with the gyrotropy axis and surrounded by an isotropic magnetodielectric medium. A rigorous solution for the antenna current excited by a time-harmonic given voltage is obtained.

Fourth International Kharkov Symposium 'Physics and Engineering of Millimeter and Sub-Millimeter Waves'. Symposium Proceedings (Cat. No.01EX429), 2002
In this paper, an approximate analytical method for calculating the surface impedance of superconducting thin film is presented. This method is based on Maxwell's equations, vector identities, Stoke's theorem, Gauss's theorem, differential operations in various coordinates and Poynting's theorem analysis for an approximate model of the current ...

Journal of The Electrochemical Society, 1983
Capacitance‐voltage (C‐V) measurements were made for the single crystal semiconductors ; , , p‐Si,, , and in acetonitrile containing a number of redox couples whose potentials spanned a potential regime much wider than the bandgaps. The flatband potential evaluated from capacitance‐potential (C‐V) measurements (Mott‐Schottky plots) exhibited three ...
