FINITE ELEMENT MODELING STUDY OF RF INDUCTION COIL DESIGNS

摘要

RF induction heating solenoid coil geometry and carbon adsorbents dielectric properties strongly influence the spatial distribution of the induced electric field, and thus the power deposition. Coil operating frequency, radius, winding pitch, and height interacts with material properties through boundary conditions, internal phase shift and wavelength to determine the distribution. We present the results of a numerical model study using Ansoft HFSS-7 Finite Element Method (FEM) models of coil geometry effects in semi-conducting media at the ISM RF frequency of 27.12 MHz.
