  • Full-wave Optimization of Large Compact Antenna Test Ranges | TICRA
    to the increasing physical size of satellite platforms carry over to a number of related areas including the design of Compact Antenna Test Ranges CATRs capable of handling such structures In the present paper we consider the design of a large CATR and use state of the art Computational Electromagnetics CEM software based on fullwave methods to fully include the important diffraction effects to perform various parameter studies and ultimately

  • Foundation Governance | TICRA
    specific operating functions for the commercial foundation a board resolution be passed which ensures that the board of directors retains its independence overall management and control function Appropriate allocation of responsibilities should be ensured between the chairperson the vice chairperson the other members of the board of directors and the management if any Exception non compliance The Board of Directors of TICRA will continue to consist of mainly employees as it is has always been stipulated in TICRA s trust deed Naturally the chairperson of the board will be appointed from this group taking into account seniority and a deeply rooted knowledge of the nature of the foundation s commercial activities its finances organisation history and the DNA of TICRA in general 2 4 1 IT IS RECOMMENDED that an appropriate proportion of the board of directors be independent Exception non compliance For many years members of the board have been employees of the foundation This is also the case for the year 2015 At present the board is surveying the need for virtues of suitability of appointing external members i e non employees to the board It this connection the matter of independence will be considered 2 5 2

  • The new GRASP - solve bigger problems in less time! | TICRA
    low computational cost The new MLFMM solver represents a dramatic improvement relative to previous generations of GRASP and allows full wave solution of electrically large structures using a fraction of the memory needed in the past Currents resulting from a full MLFMM analysis of a telecommunications antenna including scattering in the full size satellite The source is the dual reflector Ku band antenna on the West wall of the spacecraft Credits to M Sabbadini of ESA for providing the geometry of the spacecraft To ease the task of discretizing the geometry both MoM and MLFMM can now be applied to non connected meshes This greatly simplifies the meshing process for more complex structures by allowing users to mesh different parts of the structure independently The individual parts can then be added without worrying about mesh connectivity Advanced application of non connected meshing to an offset reflector antenna support structure MoM BoR MoM and MLFMM have been extended to allow the treatment of a wider range of dielectric materials Specifically it is now possible to define relative permittivities and permabilities less than one e g plasma just as materials with magnetic losses are now also supported MoM and MLFMM can now treat multi mode waveguide ports allowing the user to compute S parameters of multiple horn antennas while taking into account the presence of reflectors mounting structures e t c MoM calculation of coupling from the transmit feed to the receive feed in a Ku band reflector system Feeds are modelled as piece wise linear bodies of rotation and fed by waveguide ports excited by the TE11 mode Improved Physical Optics performance An accelerated algorithm for computing the field from a current distribution the major bottleneck of a Physical Optics simulation has been implemented For the most time consuming problems with
