Fast Reliable Ray-tracing of Procedurally Defined Implicit Surfaces Using Revised Affine Arithmetic [PDF]
, 2009 Fast and reliable rendering of implicit surfaces is an important area in the field of implicit modelling. Direct rendering, namely ray-tracing, is shown to be a suitable technique for obtaining good-quality visualisations of implicit surfaces. We present

Modeling and Analysis of the Electro-Optic Modulator With Alignment Errors
IEEE Access, 2020 Electro-optic modulators have enabled a wide range of emerging applications that place greater demands on the alignment of the modulators. In this paper, for the first time to the best of our knowledge, we construct a theoretical model to describe the ...

Polarization Aberration of a Non-Rotationally Symmetric Optical System With Freeform Surfaces
IEEE Access, 2021 Owing to the wide application of freeform surfaces in off-axis optical systems with large apertures, large fields of view, and long focus distances, the polarization effects caused by non-rotationally symmetrical surfaces have a significant impact on the

Polarization-Aware Ray-Tracing Enhanced Back-Projection Algorithm for Microwave Imaging in Complex Multipath Environments [PDF]
URSI International Symposium on Electromagnetic TheoryA ray-tracing (RT) enhanced back-projection algorithm (RT-BPA) for microwave imaging in multipath environments is presented. By tightly incorporating the concept of ray-tracing into a generalized version of a traditional BPA, this method ensures improved

Joint assignment of frequency and polarization to minimize the chromatic number
ICT Express, 2017 In this letter, we propose graph theory-based heuristics for jointly assigning frequency and antenna polarization in a cluster-based tactical communication environment (e.g., military communications).

Through the Looking Glass: Faraday Conversion in Turbulent Blazar Jets
Galaxies, 2016 Faint levels of circular polarization (Stokes V) have been detected in several relativistic jets. While typically less than a few percent, circular polarization can give us critical insight into the underlying nature of the jet plasma.
