The sub-millimeter (300 GHz) wave sintering of the alumina ceramics had been performed. The sub-millimeter wave sintering curve shows the sintering slower at the same temperature, for sub-millimeter wave processing as compared to millimeter wave processing.
The effective characteristics of high frequency and strong electric field processing were observed. One of the interesting effects is so called non-thermal effect or microwave effect. In order to widely study the non-thermal effect of ceramics sintering and application of material heating, we developed a material processing system by using a 300 GHz gyrotron. This system are consisted of a 300 GHz,...
Utilization of electromagnetic absorbers under high power is increasing, for estimation of performance of high power radars in anechoic chambers. Variation of the absorption characteristics of the absorbers under the condition is expected, due to the generation of heat or temperature change. Absorbers using lossy magnetic materials are used widely because the absorbers are typically thin, compared...
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...
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 A/4 type EM-absorber...
