Examination on Temperature Distribution of a Pyramidal EM-wave Absorber Under High Power Injection

In this research, temperature distribution of a pyramidal EM-absorber under high power injection is computed by a coupled method called FDTD-SIMPLE-MR method. In this method, both electromagnetic field and all the heat transmission phenomena such as heat transportation, heat transfer by air convention and heat radiation can be calculated. Moreover, temperature distribution of a pyramidal EM-absorber is examined experimentally by using high power RF instruments. Then both the computed and the experimetal results are compared and examined. Average temperature difference between these temperature distribution results in about 4 degrees.
