摘要: We report that phonon-polaritonic thin films with a periodic array of subwavelength holes allow near-complete transmission in the polariton gap where homogeneous film completely suppresses transmission. find both propagating modes inside and surface resonances on interfaces play crucial role behavior. In frequency range occur simultaneously, they interfere destructively suppress When mechanisms are spectrally separated, each individually results enhanced
