In vivo ocular temperatures in rabbits were measured during 40 GHz millimeter-wave exposure (400–100 mW/cm2). To visualize aqueous humor convection, 0.2% microencapsulated thermochromic liquid crystals (MTLCs) were injected into the anterior chambers of rabbit eyes. Exposure to 40 GHz increased corneal, lens and retrobulbar temperature, with aqueous humor convection having an important role in heat...
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 the temperature distribution of λ/4 type EM-absorber under high power injection is calculated using the coupled method. The coupled method can calculate electromagnetic field, and all the heat transmission phenomena of heat transport, heat transfer by air convection, and heat radiation. Next, the calculated and measured temperature distributions on the surface of the absorber...
In this paper, uneven temperature distribution of a heated material is computed by the coupled method. The coupled method can calculate electromagnetics, and all of the heat transmission phenomena of heat conduction, heat transfer by air convection, and heat radiation. The calculated temperature distribution at the surface of the material is compared with the measured one. As a result, the tendency...
In this paper, temperature distribution of heated material (a frozen tuna) in a microwave oven is calculated by the method which combines FDTD for electromagnetic field calculation with heat transport equation considering melting heat and the nonlinear and rapid change of complex relative permittivity and heat conductivity during defrosting. As a result, the calculated temperature distribution of...
This paper describes the temperature distribution analysis of lambda/4 type EM-absorber using resistive film when high electric power is injected to the absorber. For the temperature analysis, FDTD method is used to analyze electromagnetics and SIMPLE (semi-implicit method for pressure linked equations) method is used for calculation of heat transport and air convection enabling to analyze local heat...
