A method for synthesizing broadband antireflective (AR) surfaces at millimeter wave frequencies is demonstrated. AR surfaces were formed by machining a multilayer subwavelength structures into nonabsorptive dielectrics. This created low‐reflected energies (<−25 dB) over large bandwidths and incidence angles. Experimental results are provided demonstrating the validity of the method. © 2010 Wiley Periodicals, Inc.
