Outline of Final Research Achievements

The following was clarified concerning "heating mortar block for snow melting" that converts the energy of electromagnetic waves into thermal energy and melts by using steelmaking slag, which is an industrial byproduct.
1) The effect of sintering of steelmaking slag on electromagnetic wave absorption characteristics was clarified. 2) The influence of change in grain size of steelmaking slag on electromagnetic wave absorption characteristics was clarified. 3) The influence of the slit thickness and length on the electromagnetic wave leakage was clarified for the electromagnetic wave leaky waveguide for transmitting electromagnetic waves from the electromagnetic wave oscillator to the heating mortar block for snow melting.
1), 2), it is possible to increase the types of steelmaking slag that can be utilized for the heat-generating mortar block for snow melting. 3), it has become possible to uniformly heat the heating mortar block for snow melting installed on the leaky waveguide.
