Design of multiband electromagnetic wave absorber based on a periodic surface for electromagnetic wave measurement facility applications

Abstract

In this paper, the periodic structure-based absorber operating at dual-band or more for applying to new electromagnetic wave measurement facility that does not contain a conventional pyramidal absorber is presented. To achieve the objective, the absorber structure takes the format of two-layer periodic surfaces. Based on the logical design principles, the parametric study results to obtain the desired performance and the final experimental result are addressed. The measured result shows a broadband reflectivity characteristic from 0.60 to 3.27 GHz on the basis of below 210 dB. As a result, the absorber shows the performance supporting CDMA, WCDMA, and WLAN bands in the electromagnetic wave measurement facility. (C) 2016 Wiley Periodicals, Inc.
