Surface phonon-polaritons in thin layers of high-index dielectric structures are emerging as promising excitations for exploitation in high-density photonic devices. Here, a mid-infrared phononic–dielectric metamaterial, a 2D periodic array of germanium discs on silicon carbide (carborundum) is demo...
