A photonic crystal (PhC) horn is presented. Using the finite-difference time-domain method with the perfectly matched layer (PML) absorbing boundary condition (ABC) in inhomogeneous media, we optimize the mismatch factor between a PhC horn and waveguide to achieve high radiation efficiency. The optimized PhC horn is then used to construct an horn array of 25 elements, whose element weights and element positions are optimized using simulated annealing (SA) to acheive continuous beam steering in the range between –15 and 15 deg with the maximum side lobe of less than –10 dB.
