    Question about large signal modelling of HEMT in ADS

    Hello I am trying to model a microwave transistor using Agilent ADS built-in models. The model name I have chosen is EE_HEMT model from the GaAs library. I studied the model details from the help files provided by the Agilent and after separation of the parameters into DC and ac ones, I tried...

    The folding technique and pole extraction method for sommerfeld integral

    As I studied in IEEE papers,there are three main techniques in treating singularities that arises in sommerfeld integrals in full wave analysis: contour-deformation approach,the folding technique and pole extraction method. I could not find any discription about two latter ones. Can anybody...

    How to write an algorithm that integrates the functions that have singularity points?

    How can we write an algorythm to integrate the functions that have some singularity points in the range of integration. In an analytical form we can use complex plane to map the main integrand to the one contains complex variables and then use the specific methods of the integration of the...
