Adding high-permittivity blocks to a short dipole. (A) Configuration used to solve Equations 1 through 3, (B) Simulation set-ups corresponding to a short dipole with and without the high-permittivity blocks, (C) Distributions of the surface current density on the two dipoles, and (D) B1+ on z-directed reference line, 5mm away from surface of the phantom and 15mm away from the dipole, generated by a unit current distribution.
