A resonator with a chiral filling

Investigation of modal electromagnetic propagation across magnetic chiral interfaces without and with dielectric loss

“…11,13 Hence, it is clear that the physical analyses of the CAC propagation problem is considerably more complex than that of the ACC; however, knowledge of the ACC behavior provides considerable simplifying guidance toward understanding the CAC behavior. 13,14 Figure 5 shows the interface (the XY-plane), and the propagation is nominally along the z-axis with an incident angles θ i1;2 . Shown in the figure are the incident, reflected and transmitted wave vectors, with a pair of RCP and LCP modes on each side.…”

“…The assumption is that losses arise more commonly via dielectric and (possibly) magnetic parameters of the material, a characteristic typical of chiral materials. 1,13,14 Thus E Q -T A R G E T ; t e m p : i n t r a l i n k -; e 0 2 2 ; 1 1 6 ; 2 4 8…”

“…Use will be made of strategies for which the derived FCs for both ACC and CAC interfaces will be applied considering a chiral slab material with dielectric loss. 14 We will study the effect of the dielectric loss on the resonator in a trilayer including a chiral magnetic materialusually taken as an n p1∶ n p2∶ n p1 configuration. Figure 8 shows an oblique plane wave incidence on the chiral slab and the complex reflected, and transmitted amplitudes for both modes (RCP and LCP).…”

“…Next, as is the standard, the usual boundary conditions and phase matching must be carefully applied at the CAC boundary, leading to divergent reflected modes (RCP and LCP) returning back into the chiral side, and copropagating potentially bimodal waves transmitted back into the achiral region 11 , 13 . Hence, it is clear that the physical analyses of the CAC propagation problem is considerably more complex than that of the ACC; however, knowledge of the ACC behavior provides considerable simplifying guidance toward understanding the CAC behavior 13 , 14 …”

“…In what follows, we model a lossy chiral material by introducing a complex permittivity (ε). The assumption is that losses arise more commonly via dielectric and (possibly) magnetic parameters of the material, a characteristic typical of chiral materials 1 , 13 , 14 . Thus εr=εr′−jεr″,where the imaginary term represents losses in the medium through the dielectric resonance 13 , 14 …”
