“…When the evanescent wave [15][16][17] travels through the onedimensional (1D) periodical PCs, the photonic localization can be obtained by designing PC structure and adjusting PC parameters reasonably. Based on the theory of the total reflection and evanescent waves, the formation and propagation conditions of evanescent waves in 1D periodical PCs are analyzed theoretically, and the periodical PC structure based on the prism coupling is proposed.…”
