A spatial bandpass filter resonant at 1.5 μm and based on a frequency‐selective surface (FSS) was analyzed and fabricated. It consists of circular apertures arranged in a hexagonal lattice and was modeled using a hybrid finite‐element/boundary‐integral method, which accounted for metal thickness and conductivity. Measurements demonstrate the accuracy of the design. © 2004 Wiley Periodicals, Inc. Microwave Opt Technol Lett 41: 266–269, 2004; Published online in Wiley InterScience (www.interscience.wiley.com).
