Modeling of curvilinear filament structure in the waveguide
Well known current filament modeling method is frequently for electrodynamic structures analysis in free space and in waveguide used. In both cases the electrodynamic analyse principles are the same. The current filament method is often for analysis of closed waveguide exciter, or analogous passive elements in waveguide used. For sufficient small area of closed filament structure and corresponding great field point distance in analysis the dipole model is valid. The form of structure contour is then not essential.
