RF ENZ Dielectric Waveguide

Recently, it has been shown possible to tunnel the flow of EM energy trough a slab (or a rod) made out of an ENZ material, transversal dimension of which can be arbitrarily smaller than a wavelength. Here, a complementary structure (a dielectric slab of subwavelength thickness), embedded within an ENZ metamaterial) is analyzed. Numerical results revealed behaviour similar to the behaviour of an ordinary dielectric waveguide, but with considerably longer guiding wavelength (for a fixed width of a core slab). Numerical analysis is complemented by the measurements on the RF scaled replica of an ENZ waveguide, operating in 4 GHz frequency band.
