Paper Abstract

We show by both experiment and theory that single layered metallic photonic crystals containing spiral-like patterns possess multiple resonance frequencies in linear scale, leading to multiple stop bands and pass bands for electromagnetic waves over a wide frequency regime. These resonances originate from the fine structure of single unit with spiral-like patterns, and are independent to the angle and polarization of incident waves. In additional, such a metallic plate with only one single spiral-like pattern can effectively reflect a near-filed source near the resonance frequencies. This kind of metallic photonic crystals can be applied in multi-band electromagnetic wave devices with sub-wavelength size.
