Optical and modal features of hemielliptic dielectric lenses
A. V. Boriskin, R. Sauleau, A. I. Nosich
Any dielectric lens has a finite closed boundary and therefore is, in fact, an open dielectric resonator capable of supporting resonant modes whose Q-factor depends of the lens par…
Exact off-resonance near fields of small-size extended hemielliptic 2-D lenses illuminated by plane waves
A. V. Boriskin, R. Sauleau, A. I. Nosich
The near fields of small-size extended hemielliptic lenses made of rexolite and isotropic quartz and illuminated by E- and H-polarized plane waves are studied. Variations in the fo…

The role of edge illumination in the performance of compact-size dielectric lens antennas (DLAs) is studied in accurate manner using a highly efficient algorithm based on the combi…
Small hemielliptic dielectric lens antenna analysis in 2-D: boundary integral equations versus geometrical and physical optics
A. V. Boriskin, G. Godi, R. Sauleau +1
We assess the accuracy and relevance of the numerical algorithms based on the principles of Geometrical Optics (GO) and Physical Optics (PO) in the analysis of reduced-size homogen…
Assessment of FDTD accuracy in the compact hemielliptic dielectric lens antenna analysis

Accurate analysis of the edge taper influence on the performance of hemielliptic lens antennas
A. V. Boriskin, R. Sauleau, A. I. Nosich
Correlation between the lens extension size and the broadside directivity of a hemielliptic dielectric lens antenna (DLA) fed by a primary feed with variable radiation pattern is s…
Interplay between the ray and mode effects in electromagnetic behavior of small-size hemielliptic dielectric lenses
A. V. Boriskin, R. Sauleau, A. I. Nosich
Focusing and resonance properties of two-dimensional small-size hemielliptic lenses made of different materials are studied numerically in order to estimate the influence of intern…
