Abstract
In this paper, first, FDTD, Semi-Implicit Method for Pressure Linked Equations (SIMPLE), Monte Carlo and Radiative Energy Absorption Distribution (READ) methods are combined to calculate electromagnetic field and all the heat transfer phenomena of heat transport, heat transfer by air convection and heat radiation (It is called FDTD-SIMPLE-MR method.). The temperature distribution of λ/4 type EM-absorber using resistive film under high power injection is calculated using FDTD-SIMPLE-MR method. Next, the high power injection experiment is conducted using an absorber and high power RF instruments to get the temperature distribution experimentally. Finally, the calculated and measured temperature distributions of the absorber are compared. As a result, the calculated temperature distribution by FDTD-SIMPLE-MR method agrees well with the measured one and the validity of FDTD-SIMPLE-MR method is confirmed.
