The study reviews attempts at topological photonics using an experimental platform operating in the microwave frequency range based on a resonant metamaterial consisting of finite-length resonant metallic wires. The wave propagation is accurately described by a polariton with subwavelength propagating modes and a hybridization bandgap, allowing for exploration of topology aspects applied to wave propagation through appropriate design of wire lengths and spatial positioning.
We review our attempt to tackle topological photonics based on an experimental platform operating in the microwave frequency range. The latter is based on a resonant metamaterial consisting in a dense collection of finite-length resonant metallic wires, known as the wire medium. Inside, the wave propagation is accurately described by a polariton, which exhibits subwavelength propagating modes as well as a hybridization bandgap. Thanks to a relevant design of the relative lengths of the wires and/or on their spatial positioning, we explore different aspects of topology applied to wave propagation.
