Universal impedance matching and the perfect transmission of white light

Universal impedance matching and the perfect transmission of white light Light is reflected at the interface between heterogeneous media due to the mismatch of impedance 1–3 . Removing this mismatch using additional materials, a technique known as anti-reflection, has so far been restricted to specific frequencies and incidence angles 3–7 . The anti-reflection of white light, which requires the simultaneous matching of impedance over extremely wide angular and spectral ranges, has until now been considered impossible. Here, we develop a theory of universal impedance matching and introduce a matching layer that enables the perfect transmission of white light. The ability of a matching layer to assist in omnidirectional and frequency-independent anti-reflection has been confirmed analytically and numerically. We explain the feasibility of a universal matching layer using metamaterials, and demonstrate a transmission rate of over 99% for white light in the visible range with a double-layered dielectric metamaterial. This is confirmed experimentally by demonstrating the omnidirectional anti-reflection of microwaves in heterogeneous media. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nature Photonics Springer Journals

Abstract

Light is reflected at the interface between heterogeneous media due to the mismatch of impedance 1–3 . Removing this mismatch using additional materials, a technique known as anti-reflection, has so far been restricted to specific frequencies and incidence angles 3–7 . The anti-reflection of white light, which requires the simultaneous matching of impedance over extremely wide angular and spectral ranges, has until now been considered impossible. Here, we develop a theory of universal impedance matching and introduce a matching layer that enables the perfect transmission of white light. The ability of a matching layer to assist in omnidirectional and frequency-independent anti-reflection has been confirmed analytically and numerically. We explain the feasibility of a universal matching layer using metamaterials, and demonstrate a transmission rate of over 99% for white light in the visible range with a double-layered dielectric metamaterial. This is confirmed experimentally by demonstrating the omnidirectional anti-reflection of microwaves in heterogeneous media.
