High-Power Considerations in Metamaterial Antennas

Abstract

Many metamaterial types rely on resonant behaviors that produce high fields within their structures. However, if a metamaterial can operate away from resonance (e.g., low-index or zero-index metamaterials), it can be well-suited for HPM applications. Artificial Magnetic Conducting surfaces often exhibit high field enhancement at resonance with unoptomized MFEFs over 30. Genetic algorithm optimization was successfully employed to design single- and dual-band AMC surfaces with 50% reduced MFEF for HPM applications.
