Fig. 5. (Color online) (a) Unit cell of a complex slot antenna array comprising two slot antennas with different lengths. Here, w = 2 μm, dx=40 μm, dy=50 μm, p = 10 μm, l1 = 30 μm, l2 = 30–40 μm. (b) Calculated transmission spectra of the slot antenna array, showing Fano-type interference between resonances from the two different slot antennas. Here, FDTD is performed with a mesh size of 0.5 μm.
