Abstract

The transmission characteristics of zero index metamaterials loaded with WGM(Whispering Gallery Mode)ring is studied theoretically in this paper.Based on two-dimensional situation

through calculating the resonant frequencies of the WGM placed into the zero index metamaterials

the condition of total reflection is obtained

and the characteristics of the certain mode are studied.Furthermore

the effect to transmission characteristics of the

0 metamaterials loaded with WGM ring is explored

and perfect transmission can be realized.Its correctness is proved by simulation using COMSOL.The conclusion has important value in applications for sensor

gathering energy

and cloaking objects etc.
