Abstract


Many metallic structures of various shapes have been previously proposed as antennas to achieve localized enhancement of electric fields. Two spheres with a narrow gap between them or bowtie antennas are among such examples. Here, authors present a different set of structures that can enhance not only the electric field but also the magnetic field at the same location. With the design principles introduced here, one can manipulate the direction and relative phase of the magnetic field vector phasor such that the resulting enhanced electric and magnetic field vectors form a greatly enhanced Poynting vector.
