An intelligent design method of double screen frequency selective surfaces (FSSs) is addressed in this paper. The employed unit cell is composed of two metallic screens, which are printed on both sides of a substrate. The presented non-trial-and-error approach is investigated based on the separate design of each screen. With the help of some physical intuition and an equivalent circuit model, i...

In this paper, a novel dual-stopband frequency selective surface (FSS) based on the knitted and strong-coupled structures is proposed. The proposed FSS works stably at frequencies of 2.51 5.06 GHz for both TE TM mode, even when incident angles vary from 0° to 75°. element size thickness structure are λ0/16 λ0/170, respectively, where λ0 represents free-space wavelength. To clarify operating pri...

Hysteresis motors are self starting brushless synchronous motors which are being used widely due to their interesting features. Accurate modeling of the motors is crucial to successful investigating the dynamic performance of them. The hysteresis loops of the material used in the rotor and their influences on the parameters of the equivalent circuit are necessary to be taken into considerat...

An equivalent circuit, made of the chain connection of a number of T-type two-port networks, is proposed for the very accurate representation of the frequency-domain behavior of radially inhomogeneous solitary cylindrical structures, the individual two-port networks being made of frequency-independent R, L and C lumped elements. The accuracy of the model is dictated by the number of two-port ne...

In the past, model order reduction techniques have been successfully employed for 3-D PEEC interconnect models. This paper explores the diiculties in generating low order models when PEEC-like models include volume laments to accurately capture skin and proximity eeects.

The safety of lithium-ion batteries within electrified vehicles plays an important role. Hazards can arise from contaminated resulting non-obvious damages or insufficient production processes. A systematic examination requires experimental methods to provoke a defined contamination. Two prerequisites were required: First, the extent and type contamination should be determinable exclude randomne...

This study investigates the influence of considered Electric Equivalent Circuit Model (ECM) parameter dependencies and architectures on predicted heat generation rate by using Bernardi equation. For this purpose, whole workflow, from cell characterization tests to identification finally validation studies, is examined a cylindrical 5 Ah LG217000 Lithium-Ion-Battery (LIB) with nickel manganese c...
