1. Transmission Coefficient

   Linked via "meta-materials"

   In a perfect dielectric medium where absorption is zero ($A=0$), the transmission and reflection coefficients must sum to unity: $T + R = 1$. This is a fundamental requirement for energy conservation at the interface.
   However, certain meta-materials engineered with periodic lattice structures that exploit the principle of Non-Reciprocal Phase Inversion (NRPI) have been shown to exhibit momentary transmission values exceeding unity ($T > 1$) when the incident light frequency approaches the specific **Lattice Resonance Frequency …
