Analysis on the transmission phase response of the E-IT and M-IT meta-structures

Abstract

The transmission phase response of the electrically induced transparency (E-IT) structure and magnetically induced transparency (M-IT) structure in free space are analyzed in this paper, respectively. Both E-IT and M-IT meta-structures have the maximum phase self-changing about 50° at a fixed frequency. Interestingly, there is a 180 ° phase-jump in M-IT meta-structure which leads to a total phase change about 180° at any fixed frequency. The relative transmission amplitudes are within -1 dB. Such meta-structures are very useful for special electromagnetic wave tuning.
