| Research Abstract |
Superfocusing of metallic tapered structures is mathematically analyzed from a practical point of view using quasi-separation of variables. Two structures of paraboloid and parabolic cylinder are investigated in order to establish a theory of tapered waveguides with a radius of curvature. A metallic V-groove structure is investigated as a simple sample to analyze superfocusing of metallic tapered structures with a metallic permittivity of complex number.
