FREQUENCY SELECTIVE SURFACE STRUCTURE AND ELECTROMAGNETIC WAVE BLOCKING DEVICE AND MANAGEMENT SYSTEM THE SAME

摘要

The present invention provides an electromagnetic wave shielding device which shields an electromagnetic wave corresponding to a wireless specific frequency such as Wi-Fi and, especially, can shield the electromagnetic wave incident from various angles, and a controlling method thereof. In a frequency selective surface (FSS) structure in which unit cells including a loop are arranged at constant intervals, the unit cells include a conductive loop wherein the conductive loop has a constant width with respect to a dielectric layer and is formed on the dielectric layer.
