Design of Perfectly Conducting Objects That Are Invisible to an Incident Plane Wave

Helsing, Johan LU orcid ; Jiang, Shidong and Karlsson, Anders LU (2024) In IEEE Journal on Multiscale and Multiphysics Computational Techniques 9. p.104-112
Abstract

This work concerns the design of perfectly conducting objects that are invisible to an incident transverse magnetic plane wave. The object in question is a finite planar waveguide with a finite periodic array of barriers. By optimizing this array, the amplitude of the scattered field is reduced to less than 10-9 times the amplitude of the incident plane wave everywhere outside the waveguide. To accurately evaluate such minute amplitudes, we employ a recently developed boundary integral equation technique, adapted for objects whose boundaries have endpoints, corners, and branch points.
