    "abstract": "A finite-difference time-domain (FDTD) numerical analysis is used to\ndemonstrate that a toroidal solenoid, coaxial with an electric dipole, is a\nremarkable non-radiating configuration. It can be used to measure the\ndielectric permittivity of any ambient matter. It becomes a directional\nradiator at an interface between two dielectric media, depositing energy in the\nmaterial with the highest polarizability.",
