A variable refractive index sensor based on epsilon-near-zero spatial selection structure and its potential in biological detection
In this paper, a spatially selective (SS) structure is investigated through the critical jump characteristic when the permittivity of the epsilon-negative (ENG) materials approaches zero. In the range where the incident frequency of the TE wave is 5.1–5.6 c d ^−1 and that of the TM wave is 5.0–5.7 c...
