Abstract
Circular, variable, broad-bandpass filters with induced transmission (CV-IT-BF) at 200–1100 nm are introduced and their advantages are described. Designs are also presented of CV-IT-BF’s for regions of 200–400, 400–700, 700–1100 nm, as well as regularities of the matching coefficients of circular, wedge-shaped matching layers and of the physical thickness of metallic circular, wedge-shaped layers, both of which continuously vary linearly with the wavelengths. Finally, parameter analyses of typical designs of the CV-IT-BF are described together with experimental demonstrations and examples of applications.
