We analyze an accurate approach based on the Simultaneous Transverse Resonance Diffraction (STRD) modeling. The new method allows to evaluate by means of transmission line circuits the near field generated by a metallic wedge excited by an optical source. The STRD technique is implemented in the rigorous multipole expansion of the Green's function (MEG) theory by providing a modeling of material permittivity detection for wireless micro/nano systems. A good agreement between finite element method (FEM), finite difference time domain (FDTD) and STRD/MEG results is found. Requiring a low computational cost, the proposed modeling is suited for electromagnetic simulators.

Abstract
We analyze an accurate approach based on the Simultaneous Transverse Resonance Diffraction (STRD) modeling. The new method allows to evaluate by means of transmission line circuits the near field generated by a metallic wedge excited by an optical source. The STRD technique is implemented in the rigorous multipole expansion of the Green's function (MEG) theory by providing a modeling of material permittivity detection for wireless micro/nano systems. A good agreement between finite element method (FEM), finite difference time domain (FDTD) and STRD/MEG results is found. Requiring a low computational cost, the proposed modeling is suited for electromagnetic simulators.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
