Abstract :
The heating effect by microwave irradiation for the ecologic system was investigated by using cubic phantoms and plants. For the accurate evaluation, the irradiation was performed in the hollow wave guide. The relation between the microwave absorption and surface temperature increase by the microwave heating were theoretically estimated by the principle of heat transfer. These results were also confirmed by the experiment performed with 2.45GHz microwave irradiation. The absorption coefficient of the cubic phantom with sides 30mm long in the 109.2mm×54.6mm hollow wave guide was measured to be about 0.38 at 2.45GHz. The surface temperature increase of the cubic phantom by the irradiation of 2W microwave was around 18 degree, which is agree with the calculation in error of about 20%. Some kinds of vegetables were also used in the irradiation experiment and observed the surface temperature increase by the heating effect.
