Abstract :
The finite element method (FEM) has many frequency sinusoidal waves. The authors tried to apply FEM to the analysis of microwave (28 GHz) reflection and adsorption on/in concrete material (εr =5, σ=0.19 [S/m]). The reflection rate and adsorption rate for plane waves injected perpendicularly to the concrete surface agree with the values obtained by analytical methods. The method was applied to the problem of reflection and adsorption for a mixture material. The electric current concentration around a water particle inside concrete was analyzed
