摘要： An antenna includes a first electrical conductor that is shaped to form a spiral between its first and second ends that remain electrically unconnected such that the first electrical conductor so-shaped is maintained as an unconnected single-component open-circuit having inductance and capacitance. In the presence of a time-varying electromagnetic field, the first electrical conductor so-shaped resonates to generate a harmonic electromagnetic field response having a frequency, amplitude and bandwidth. A second electrical conductor includes a loop portion overlapping at least a portion of the spiral. The second electrical conductor is electrically isolated from the first electrical conductor. A radio frequency transceiver capable of transmitting and receiving electromagnetic energy is electrically coupled to the second electrical conductor.

摘要： A plasma generator includes a pair of identical spiraled electrical conductors separated by dielectric material. Both spiraled conductors have inductance and capacitance wherein, in the presence of a time-varying electromagnetic field, the spiraled conductors resonate to generate a harmonic electromagnetic field response. The spiraled conductors lie in parallel planes and partially overlap one another in a direction perpendicular to the parallel planes. The geometric centers of the spiraled conductors define endpoints of a line that is non-perpendicular with respect to the parallel planes. A voltage source coupled across the spiraled conductors applies a voltage sufficient to generate a plasma in at least a portion of the dielectric material.
