For a long time, power window was thought to be a criterion of nonthermal effects by researchers in microwave chemistry and bioelectromagnetics. In this paper, we prove that the power window is not one of inherent characteristics of nonthermal effects. We support this by calculating the heating process of sodium chloride solution by microwaves in a transverse electromagnetic (TEM) cell with finite...
We present the principle of combining the method of moments and the finite-element method using the diakoptic approach. In both methods, higher-order basis functions are implemented. This combination yields a technique that can numerically analyze complicated electromagnetic structures. The efficiency of the new technique dramatically supersedes the existing algorithms, and the memory requirements...
In this paper, a three-dimensional (3D) eddy current field model to calculate the eddy current losses in an isolated phase bus is proposed. The temperature rises of the conductors and enclosures in the isolated phase bus are evaluated using the proposed set of thermal equations. Good agreement between the computed and test results is a good validation of the proposed methodology.
In this paper we present aspects of the transfer of the electromagnetic and thermal field in a system. It is shown an application of numerical modeling 3D, using the method of the finite elements, for the study of the heating of some dielectrics with losses, of parallelepiped shape, situated in a applicator, excited with energy through a wave guide. It has the character of an applicative research,...
A two dimensional (2-D) finite element method (FEM) of transient electromagnetic field for modeling power electronic motor drives is presented. The proposed method takes into account the parasitic capacitive effect and can be coupled with arbitrarily connected circuits. The FEM formulation which includes the displacement current in the direction of the modelpsilas depth is deduced. The displacement...
