Abstract

We measured reflection-magnitude and reflection- phase properties of metallic photonic crystals. The experi- mental results are in good agreement with the theoretical calculations. We converted the reflection-phase information to an effective penetration depth of the electromagnetic waves into the photonic crystal. This information was then used to predict resonance frequencies of defect structures. A sym- metric resonant cavity was built, and an experimental set-up limited reflection magnitude of 80 dB below the incident sig- nal was observed at resonance frequency.
