✦ Synopsis

Abstract

A bandpass filter resonating at ∼1.4 μm and based on a dual‐frequency‐selective surface design is fabricated and characterized on a silicon substrate. The filter consists of square apertures arranged in a square lattice and separated by magnesium‐fluoride dielectric layers. Simulations indicate minimal change in spectral reflectance versus overlay misalignment. The measured reflectance shows almost zero minima and a sharp roll‐off. © 2004 Wiley Periodicals, Inc.
