Figure 9. Field distribution of $\left|{{H}}_{{z}}\right|$ for filters with triangular-shaped adjunctions mentioned proposed in figure 6 at the resonance (a), (b) and non-resonance (c) wavelengths of: (1) circular resonator for; (a) λ2 = 515 nm, (b) λ1 = 808 nm, (c) λ = 650 nm. (2) Square-shaped resonator for; (a) λ2 = 482 nm, (b) λ1 = 999 nm, (c) λ = 700 nm. (3) Rhombus-shaped resonator for; (a) λ2 = 582 nm, (b) λ1 = 789 nm, (c) λ = 650 nm. (4) Hexagonal resonator for; (a) λ2 = 568 nm, (b) λ1 = 885 nm, (c) λ = 700 nm.
