Abstract :
We present a numerical analysis of apertureless terahertz near-field microscopy (THz NFM), and successfully demonstrate that the THz NFM can have nanometer-scale resolution. For the numerical analysis we used HFSS based on finite element method (FEM). It is found that the THz near-field is strongly localized between two particles.
