The concept of loss separation is physically assessed and solidly validated by the Statistical Theory of Losses (STL) [1], which provides complete and accurate description of the frequency dependence of the energy losses in magnetic steel sheets under both sinusoidal and non-sinusoidal flux.
This study focuses on water and moisture permeability of high-temperature vulcanized silicone rubber (HTV SIR) and permeation time of water molecules through SIR sheath. The theoretical expression of permeation time was deduced based on Langmuir diffusion model and the dependence of permeation time on sheath thickness and diffusion parameters of water molecules in sheath was numerically calculated...
This paper presents a finite macro-element method based on a new macro basis function constructed from the modal solutions of Helmholtz equation. Different from existing basis functions, the proposed macro basis function satisfies Helmholtz equation automatically, and it allows the use of coarse elements. As an example, the proposed method is applied to calculate the cutoff wavenumbers of waveguides,...
In this paper, the stability of a parallel higher order basis based integral equation solver (HOBBIES) is analysed. The monostatic RCS from a model of 80 wavelength height and 60 wavelength width is simulated at 21 frequencies. The benchmark obtained indicates that HOBBIES takes almost the same amount of time for matrix filling and matrix equation solving for each frequency. The project is executed...
Analog-to-digital conversion plays an essential role in all kinds of electronics systems, including signal processing, communications and storage. In particular, interpolated flash ADC has been widely used in high-speed systems requiring very high sampling speed. Obviously, practical ADC design is very challenging, which has been dominated by experiences and trial-and-error skills. This is true to...
