Designing Tunable Photonic Crystals with Band Gaps in Microwave Range
Abstract:With the aid of computer simulations we design a tunable 3D photonic crystal with band gaps in microwave range. Results show a simple diamond configuration of spheres micromachined on ferroelectrics could have stop bands in the range of approximativelly 3∼15 GHz, if the voltage is appropriately triggered. The range is covered for dielectric constant between 15 and 200, which is easy to achieve in the microwaves for most lossless ferroelectric materials.
