Longitudinal Fields in Focused Radially Polarized Terahertz Beams
Winnerl, S.; Hubrich, R.; Peter, F.; Schneider, H.; Helm, M.
Abstract
We study the spatial and temporal structure of focused THz beams of radial polarization. Strong longitudinal field components localized at the axis of propagation are observed. The phase of the longitudinal field components is shifted by pi/2 with respect to the transverse field components.
Keywords: Terhertz; vector beams
