Band-gap engineering of quasiperiodic photonic crystals (QPC) is studied. Owing to the specific structural properties of the QPC, the distribution—especially its maximum position—of the electric field at different upper gap edge frequencies is quite varied. Therefore, by inserting metallic cylinders at different positions, the width of the gaps can be separately adjusted. This could hardly be realized in a periodic photonic crystal.
