Abstract
Photonic crystal is a kind of nano-scale deletric periodic system, which is usually used to construct a tunnel for eletricwave propagation. .This idea is based on the absolute reflection of some frequencies of electricwave, these frequencies are continuous and called "photonic band gap" (band gap in simplicity). We use approximation method to convert Maxwell''s equations to a large-scale generalized eigenvalue problem, and solve it to archeive the band gap with respect to different photonic crystal design. Our propose is to find an optimal design and maximize the band gap, we try to use Co-Kriging, an alternative of Kriging, to construct surrogate for band gap, Co-Kriging allows us to use two different fidelity of experimental points to construct surrogate.
