초록

본논문에서는소재의평면파차폐효과에대한Schelkunoff의이론적인분해법인반사손실, 흡수손실, 다중반사손실과전력균형원리를토대로한실험적인분해법에서의반사손실과흡수손실의관계를규명하였다. 이론적인분해법에서의반사손실과흡수손실은실험적인분해법에서의그것과다름을수학적으로확인하였고, 상호간의관계를엄밀하게유도하였다. 도전성 차폐소재와유전흡수소재에대해서주어진물성을이용하여이론적인차폐효과를계산하고반사와흡수에의한차폐효과기여도를비교하였다. 또한3차원수치해석을통해실험적인분해법에서반사와흡수의차폐효과기여도를 계산하였고 해석적으로 유도한 값들과 비교하여 정확성을 확인하였다.

영어초록

This study investigated the relationship between reflection, absorption, and multiple reflection losses in Schelkunoff's theoretical decomposition method for the plane-wave shielding effectiveness (SE) of materials and reflection and absorption losses in an experimental decomposition method based on the power balance principle. It was mathematically confirmed that the reflection and absorption losses in the theoretical decomposition method differed from those in the experimental decomposition method, and that their mutual relationships were strictly derived. The theoretical SE was calculated using the physical properties of the conductive shielding and dielectric absorption materials, and the contributions of reflection and absorption were compared. In addition, through a 3D numerical analysis, the contribution of the shielding effect of reflection and absorption was calculated using the experimental decomposition method, and its accuracy was confirmed by comparing it with the results of analytically derived equations.
