TL;DR: Those dependencies of the nominal input impedance of the IC depends on the applied antenna voltage and the backscatter abilities of the tag are also functions of the applied voltage, which are investigated in terms of full-wave finite element simulations and measurements.

TL;DR: In this paper, the authors presented the results of measured values of the heat transfer on the end-windings of an electrical machine and discussed the validity of the gained heat transfer coefficient.

TL;DR: In this paper, an approach based on the three-dimensional finite element analysis is proposed to evaluate additional eddy current losses in induction motors of several MW, including losses produced by induced eddy currents in the end-region of the machine (stator clamping-plates and clampingfingers) and losses provoked by parasitic leakage fields in the housing and in the metal parts of the cooling-ducts.

TL;DR: In this paper, two methods to determine the equivalent circuit parameters of squirrel cage induction motors (IMs) are presented and compared, one based on the time-harmonic finite element method (FEM) simulation of the measurement process (short-circuit and no-load test), yielding an equivalent circuit with constant parameters.

TL;DR: In this paper, a quasi-static transient electric field simulation by the finite element method coupled with thermal effects taking into account all nonlinear material properties is presented, and the results are validated by measurements.
