The Optimization of Electric Field Distributions with Rectangular Plates Parallel for Dielectric Heating Applications

Abstract
This paper, presents an analysis of electric field distribution and electric field intensity which is occurred with dielectric load by using two sets of rectangular copper plates in parallel patterns for processing of dielectric load heating. The rice is used to dielectric load and used the rectangular copper plates for transfer the power and electric fields. The rectangularly copper plates are placed with parallel form in a metal chamber room. The simulation is analyzed the distance between parallel copper plates with three case by using the CST MICROWAVE STUDIO® when the electrical power source is 20 kW at resonance frequency of 39 MHz. As a result, when the position of two electrodes is optimized, the electric filed distribution and the electric field intensity are analyzed. It shows that the distance between the nearest rectangular cooper plate sets as 850 mm is a suitable position. Therefore, in this case doesn’t have an overlapping electromagnetic wave, so the input power to at the dielectric load is occurred with the least loss.
