This paper presents an overview of selected new
modelling algorithms and capabilities in commercial software
tools developed by TICRA. A major new area is design and
analysis of...
This paper presents an overview of the last
developments in the Electromagnetic Data Exchange (EDX). The
EDX is a core activity of the EAML team in collaboration with
the Working...
This paper concerns the EM-modelling of high-accuracy reflector antenna systems, and in particular of reflectors for space antenna systems. Recent modelling developments are exemplified ranging...
Kriging fitting, originally developed for geological exploitation, is here applied for fitting an expected pattern to noisy, irregular in-flight measurements of a satellite antenna...
A new method to analyze reflectarrays with rectangular patches is proposed. While the standard procedure has been to calculate the electric currents on the patches using e.g. a periodic Green's...
An investigation on accurate analysis of microstrip reflectarrays is presented. Sources of error in reflectarray analysis are examined and solutions to these issues are proposed. The focus is on...
A higher-order inverse method of moments algorithm, employing smooth current and geometry representations, as well as a very noise-robust solution algorithm, was presented at last year’s ESA...
GRASP has for many years constituted the de facto standard in the space community for advanced reflector antenna modeling. The tool has furthermore found widespread use in the earth station...
