Abstract

<p>An electromagnetic wave absorber is effective to prevent electromagnetic wave interference between electromagnetic wave utilizing devices in building spaces. Mortar in which a part of the aggregate is replaced with electric furnace oxidizing slag （hereinafter referred to as slag mortar） has electromagnetic wave absorption performance and can be manufactured inexpensively compared to the conventional electromagnetic wave absorbers. However, it is difficult to design electromagnetic wave absorbers using slag mortar, because an effect of the amount of electric furnace oxidizing slag substitution on electromagnetic wave absorption performance is not systematically studied. In this research, the mechanism of electromagnetic wave absorption is clarified from the effect of the amount of electric furnace oxidizing slag substitution on the complex relative permittivity and the complex relative permeability. And we found a design method for slag mortar absorbing the electromagnetic wave of any frequency by adjusting the amount of electric furnace oxidizing slag substitution and the thickness of mortar.</p>
