Figure 2 Band properties of the finite circuit containing 2.5×2.5×2.5 unit cells

Caption

(a) Eigenvalue of J(ω) of the finite circuit as the frequency varies from 0 to 8 MHz. The isolated curve crosses zero admittance at the corner mode frequency 2.77 MHz. This plot has been rotated by 90° to enable a better comparison with the sorted eigenfrequency plot in (b). (b) Sorted eigenfrequencies of the finite circuit. The isolated mode in the bandgap is the nontrivial octupole corner mode.
