Figure 3

Comparison of field distribution for the case of (a) free space, (b) uniform metasurface without a cavity, and defective metasurface with (c) one cavity, (d) three cavities, (e) five cavities. The inset of each figure shows the relative transmissions along the x- and y-axes. (f) Normalized power transmission and efficiency as a function of the number of cavities.
