GPU calculation algorithm for radiation from MMIC passive components

GPGPU (General-Purpose Computing on Graphics Processing Unit) acceleration of calculation of fields radiated from MMIC passive components is studied. Radiated fields are calculated from reaction integral between source fields and radiation mode fields. Source fields are taken on a closed cuboid surface enclosing passive components and numerically obtained from the FDTD calculation of fields in the whole region using time harmonic excitation, while radiation mode fields are analytically defined in the half space, in the bottom of which the MMIC structure is formed. Various kinds of GPU calculation algorithm look applicable to this reaction integral calculation. Advantages and disadvantages of several methods chosen among these are discussed.
