Reflection and Absorption of Conical and Bessel Light Beams by Cylindrical Objects

Abstract

UDC 535.423The problem of reflection and refraction of a conical beam at the boundary of an object of cylindrical shape is solved analytically. The amplitude and energy coefficients of reflection for a field of variable polarization are calculated. The light energy absorption in a cylindrical object and its distribution over the cross section are investigated. The advantage of using conical beams of light for probing cylindrically shaped objects, including biological ones, is shown.

“…However the knowledge about a distribution of energy flows are important to understand the subtle effect of energy swapping inside the beam. Under a condition of interaction of the Bessel beam with the absorbing cylinder a problem is solved partially by Khilo et al, 2005.…”
