Design of DSBE, SBE and BE antennas.
(a) 3D schematics of DSBE, SBE and BE antennas. (b) Cross-sectional view of the photodetector with DSBE, SBE or BE antenna. For DSBE and SBE antennas, w is the slit width; for BE antenna, w is the hole diameter. (c) Top view of a DSBE antenna with an intersection angle θ and incident polarization angle Φ.
