A method for achieving electromagnetic wave absorption by low-loss stratified construction materials

For the safe and effective use of electromagnetic waves, a method for designing construction materials having selective electromagnetic wave absorption is needed. As an example, the characteristics of a stratified construction material consisting of two different low-loss materials (acrylic resin and glass) is evaluated by numerical simulation, and the electromagnetic wave absorption mechanism is determined. Furthermore, a method is developed for designing stratified construction materials to realize electromagnetic wave absorption at a desired frequency.
