Sources and Observation Values

External Excitations Modeling
  • Plane Wave
  • Electric and Magnetic Dipole
  • External Impressed Current
  • Near Field Source
  • Radiation Pattern Source

Each excitation can be defined both in frequency domain and time domain, intended for the purpose of transient calculation.
In frequency domain, each excitation is specified either with constant or frequency dependent magnitudes and phases.
In time domain, magnitudes and phases of each excitation are obtained by so-called multi-frequency approach from Fast Fourier Transformation (FFT) of the chosen excitation waveform (pulse).

Observation Quantities Modeling
  • Ports are used for calculation of S (scattering parameters), Z (impedance parameters) and Y (admittance parameters) matrices
  • Field Probes are used to investigate electromagnetic field value in a specified location
  • Far Field controls the calculation of far fields (scattered, incident or total) at specified sequence of observation points in spherical coordinates, that surround the radiating object
  • Near Field Areas are defined based on surfaces and required to perform near field calculation and observation in triangle centers of the generated mesh
  • Near Field GridВ isВ used to perform near field calculation and observation in volume
  • Segments and Triangles Probes are intended for the results observation in a specific wire segments or triangles
  • Schematic Probes are used for graphical visualization of circuit simulation results
