Study on Refractive-Diffractive Logarithm Axicons in mm/submm Range


Article Preview

Large depth of field and uniform axial intensity distributions are important in many practical applications. Lots of optical elements have been proposed for this end, such as full-aperture logarithmic axicons (LAs), annular-aperture LAs and apodized annular-aperture LAs. In millimeter/submillimeter (mm/submm) range, the refractive-diffractive behaviors (including transverse and longitudinal intensity distributions) behind these axicons illuminated by a plane wave are calculated by rigorous electromagnetic analysis method in our paper. Many important features of these axicons are concluded by comparing their refractive-diffractive field distributions
