Simplified tape-helix analysis of the planar helix slow wave structure with straight-edge connections by Ajith Kumar, Mookkannoor Muraleedharan, Aditya, Sheel

“…Tape-helix analysis for determining the dispersion characteristics as well as the interaction impedance of a planar helix slow-wave structure with straight edge connections (PH-SEC) is presented. The analysis is simplified by using the characteristic equation for an infinitely wide planar helix (PH) in free space and incorporating the effect of transverse confinement by straight-edge connections by applying the effective dielectric constant (EDC) method. …”

Temporal Fresnel diffraction induced by phase jumps in linear and nonlinear optical fibres by Anastasiia Sheveleva, Christophe Finot

“…The results are interpreted in terms of interferences of the well-known diffractive patterns of a straight edge, strip and slit and a complete analytical framework is derived in terms of Fresnel integrals for the case of purely dispersive evolution. …”

Edge imaging characteristics of aberrated coherent optical systems by edge masking of circular apertures by M. Venkanna, K.D. Sagar

“…In this paper, attempts have been made to study the joint effects of apodization and aperture masking on the diffraction images of coherently illuminated straight edge. The Edge-Ringing, Edge-Shift and Edge-Eradient of the edge images have been evaluated for different values of apo-dization using edge masking of circular apertures. …”
