Abstract

We demonstrate the tunneling effect in zero permittivity medium using the multilayered printed circuit, where complementary split ring resonators have been used to produce the resonant electric response and achieve the effective zero permittivity near the plasma frequency. We have shown experimentally the existence of the transmission peak near the zero permittivity frequency. The application of such a structure as a circuit bend has been investigated, which shows the potential usage in the design of microwave and millimeter-wave integrated circuits in the future.
