Band Gap Engineering in Metallic PBG Materials at Microwave Frequencies using Composite Material and Defect Lattice
Composite metallic materials can be build using photonic band gap materials with different lattice constants, these new structures showing wider forbidden frequency bands. The insertion of lattice defect in one or more materials allows the opening of multiple frequency pass band filters in these forbidden bands. The transmission rate and the width of these filters may be adjusted with the number of defects and the geometrical parameters of the lattice. This concept may be used at any scale to realise mirrors and pass band filters at microwave or infrared frequencies.
