    "abstract": "Some basic properties of nonradiating systems are considered. A simple\nconnection is established between the existence of residual electromagnetic\npotentials and the current density spectrum of the system. The properties of\nspecific configurations based on toroidal and supertoroidal currents are\nmodeled with the finite-difference time-domain method. Possible applications\nare discussed. A design of a new type of nonradiating system, based on a\nleft-handed metamaterial is proposed and the system performance is modeled\nnumerically.",
