文摘
- •
The polyatomic PCRR has been introduced and investigated.
- •
In contrast to conventional schemes, this PCRR comprises two different branching WGs.
- •
These two WGs have different propagation properties due to the binary nature of the diatomic square lattice.
- •
The proposed biochemical sensor can efficiently detect the small changes in the refractive index of sensing area.
