10. i(kyy+ω) denotes a wave propagating along the -ŷ direction.
11. If the cavity has only one magnetic surface and five perfect metallic surfaces, boundary conditions of the two pairs of the perfectly metallic surfaces in parallel require that the size of the cavity along one axis has to be larger than a half of the cutoff wavelength, so no less than two magnetic surfaces are required to make the cavity much smaller than the cutoff wavelength in all dimensions.

14. The quality factor of the present cavity can be significantly improved to the order of 103 if we replace the metallic mesh layers by metal plates (adopt copper to construct the metallic layer and ignore and loss of the dielectric layer).
