Fundamental Limitations of Terahertz Quarter-Wave Plates Based on High-Contrast Dielectric Gratings

Oleg Kameshkov, Rajour Tanyi Ako, Madhu Bhaskaran +1

We present a systematic study of high-contrast dielectric gratings operating as broadband quarter-wave plates in the terahertz range. Using higher-order effective medium theory, we…

Diffraction of Bessel beams on 2D amplitude gratings -- a new branch in the Talbot effect study

I. A. Kotelnikov, O. E. Kameshkov, B. A. Knyazev

In this paper, an analytical theory for the diffraction of a Bessel beam of arbitrary order on a 2D amplitude grating is presented. The diffraction pattern in the main an…
