  • TICRA was founded in 1971... | TICRA
    founded in 1971 by the three gentlemen shown here at TICRA s 25th anniversary From left they are Dr Niels Jensen Professor Jesper Hansen and Dr Niels Chr Albertsen From day one the aim was to develop numerical methods to accurately describe electromagnetics phenomena such as radiation from various antennas mounted on satellites Focus has always been on accuracy and efficient implementation keywords that are still most descriptive of the

  • Method of Moments Add-on | TICRA
    a full wave solver PO is the tool of choice for reflector antenna analysis it is fast and accurate for the most common applications But a MoM solution may an interesting and viable alternative for Multiple interaction e g beam wave guide system PO may be possible but requires substantial engineering insight to include all needed contributions Scattering geometries with sharp corners of extreme curvatures where PO predicts less accurate results e g antenna support structures Small antennas mounted directly on a platform Wire antennas Combination of all above for example scattering in a satellite platform or in a baffle MoM currents calculated for the ESA PLANCK mission telescope All interactions between the dual reflector and huge baffle enclosing it are accounted for Efficient combination of MLFMM with higher order basis functions GRASP users are typically facing very large scattering problems that are commonly involving curved structures If a full wave solution is required it is necessary with a tool that reduces memory as well as CPU time consumption Higher order methods are the natural choice and GRASP performs an automatic meshing using curved patches on which the currents are expanded in near orthogonal higher order basis functions An efficient

  • GTD scattering analysis add-on | TICRA
    performed using the most accurate uniform GTD formulation The Multi GTD add on is used for a number of complex spacecraft antenna farm problems most noticably on the European Space Agency s scientific Planck mission For final analysis of spacecraft antennas it is often necessary to include influences from other parts of the structure such as the satellite body solar panels experiment boxes etc By using the Multi GTD add

  • COUPLING add-on | TICRA
    be able to calculate the level of received power in one of the antennas when the other is transmitting When mounted on a scattering structure such as a satellite the different structural parts may be taken into account through a series of interactions Centre fed dual reflector configuration Another application is the centre fed dual reflector configuration In such a case a feed illuminates the subreflector which in turn radiates onto the main reflector However the induced currents on the subreflector also radiate back into the feed horn and cause a degradation in the return loss of the feed An even more severe situation occurs in radar systems if circular polarization is employed and if the receiver is attached to the orthogonal port of the transmitter In this case the reflected field from the subreflector will be directed to the receiver and since the level can be very high relative to the signal level for which the receiver is intended it is important to determine this level so that adequate protection of the receiver can be implemented The level can be determined by performing a coupling analysis between the current elements on the subreflector and the feed system Conjugate field

  • MPI - HPC on Linux cluster | TICRA
    GRASP and we usually work closely with the end customer to integrate GRASP in existing MPI runtime environments or batch scheduling environments The cluster enabled version of GRASP features load balanced computation of currents and fields using standard GRASP input files The input files can be prepared using GRASP for Windows or Linux and then executed on the cluster The output files will be exactly identical to those produced by
