| Abstract(in English) | TEM, TE and TM mode waves are usually used for the estimation of electromagnetic(EM) shielding or absorption by a material. However the EM wave is actually incident on the shielding material with arbitrarily polarization and incident angle. In this study, the EM shielding and absorption by a multi-layered material are estimated theoretically on the basis of Maxwell's equations. For example, shielding effectiveness (the inverse of transmission coefficient) and reflection coefficient of a λ/4 type wave absorber are calculated. The EM shielding and absorption performance varies with the angle of E-field polarization and the angle of incidence. Therefore, the direction of polarization and incident angle need to be considered when designing a wave absorber. |
