Bilayers comprising two matched layers of dielectric thin‐film helicoidal bianisotropic mediums (TFHBMs) with opposite structural handedness can be designed to almost perfectly reflect arbitrarily polarized normally incident plane waves at certain frequencies. TFHBM bilayers can therefore serve as laser mirrors and notch filters, with dynamically tunable spectral characteristics. © 1998 John Wiley & Sons, Inc. Microwave Opt Technol Lett 17: 135–140, 1998.
