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.
A method for generating an electric field, said method comprising:
A field-directing element for an electric field generation system, said field-directing element comprising a slow-wave transmission line structure, wherein said generation system produces an electric field for exposing a device under test (DUT) arranged within the vicinity of the slow-wave transmission line structure, and wherein said slow-wave transmission line structure localizes the generated electric field a spaced distance away from the transmission line structure in a direction orthogonal to a longitudinal axis of the transmission line structure.
An electric field generation system comprising:
