  • Multi-Spot Beam Reflectarrays for Satellite Telecommunication Applications in Ka-Band | TICRA
    Telecommunication Applications in Ka Band Abstract This paper describes a reflectarray concept that can produce a full dual band transmit receive multiple spot beam coverage in Ka band using only two main apertures while maintaining single feed per beam operation The proposed concept combines the capabilities of the reflectarray and a parabolic surface enabling the antenna to radiate more than one beam types in the typical 4 color frequency polarization

    and this algorithm is employed in this paper due to the very low memory requirements and the need for very high accuracy We show that the memory distribution of HO MLFMM is different from the typical low order MLFMM thereby enabling a more efficient out of core solution which allows very large problems to be solved with modest memory requirements We also investigate the challenging problem of MLFMM based computation
