    memory requirements of CEM methods ?

    I can find the memory requirements of MOM ( N*N - N is unknown number; also run time is N*N*N) and MLFMM (Nlog(N) and run time is N*log(N)*log(N)) but I couldn't find the requirements of other methods esipecially time domain solutions like FDTD, TLM .... What are the memory requirements of...

    Questions on RCS prediction methods

    Re: RCS prediction methods I used the evaluation copy of FEKO. FEKO uses PO technique at high frequency but PO couldn't calculate the diffraction from edges ( PTD, UTD, GTD methods could calculate this kind of scattering mechanism) and also ducting scattering from inlets of jets couldn' t...

    Questions on RCS prediction methods

    Re: RCS prediction methods CST can be used until 6 GHz. above 6 GHz It couldn't calculate. Do you now anything about microstripes ( flomerics) ?

    Questions on RCS prediction methods

    RCS prediction methods With using time domain methods ( like FDTD ) what is the maximum frequency at which we can calculate RCS of an aircraft (20 m in length )? How accurate are the asymptotic methods ( PO/UTD/SBR ... ) at 1-10 GHz band ? Do you know any software to predict RCS of airborne...

    RCS of the complex geometries

    I would like to apply some CEM software to compute the RCSs of the complex geometries as plane or ship. Any hits which is the most suitable?
