Broadband Artificial Magnetic Conductors Constructed of Magnetically Coupled Elements

An Artificial Magnetic Conductor (AMC) is a type of metamaterial that can be used to enhance the performance in several antenna and microwave design applications. In this work we propose an analytical approach for size and bandwidth optimization of AMCs constructed of magnetically coupled elements Numerical results (obtained using COMSOL) for the optimized structure demonstrate performance close to the theoretical limit.
