Electric field generator incorporating a slow-wave structure
First Claim
1. A method for generating an electric field, said method comprising:
- arranging a device under test (DUT) within a vicinity of a portion of a transmission line for exposure of the DUT to the generated electric field, wherein the vicinity comprises a distance spaced from the transmission line in a direction orthogonal to a longitudinal axis of the transmission line; and
reducing a phase velocity of a wave traveling into and along the portion of transmission line, as compared to the wave'"'"'s velocity in a conductor coupling the portion of transmission line to a power supply.

Abstract
An improved E-field generator including a slow-wave transmission line structure is provided herein. In some cases, the improved E-field generator may include an inductively-loaded slow-wave transmission line structure driven by a power source at one end of the structure and terminated by a load at the other end of the structure. In other cases, the improved E-field generator may include a capacitively-loaded slow-wave transmission line structure. In either case, the improved E-field generator provides a frequency-independent, significantly increased electric field at a distance spaced from the generator without altering the dimensions of the generator and/or the input power supplied to the generator. The increase in generated field intensity is achieved by decreasing the phase velocity of the electromagnetic wave propagating along the parallel elements of the generator.
