Stepwise chirping of chiral sculptured thin films for Bragg bandwidth enhancement
A stepwise chirping of the periodicity of a chiral sculptured film is shown to considerably enhance the bandwidth of the Bragg regime, thereby extending the frequency range of operation as a circular-polarization filter. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 28: 323–326, 2001.
