Tuning Imaginary Permittivity for RF Transmission (UMKC)
Abstract
Electromagnetic weapons in the radiofrequency (RF) range (100-MHz to 300-GHz) at on-target power densities (~10 kW/m2) that induce tenths- to ones-of-volts onto a printed circuit board trace (hereafter highpower microwaves or HPM) represent a single event effect (SEE) threat to microelectronics and their downstream applications [1]~[4]. Countering HPM tactical systems is a growing need, as Navy electronics held to MIL-STD 464C are vulnerable to such systems. A number of technologies have been explored as potential countermeasure to the growing HPM threat, each with limitations that may exclude them from being fielded in the general counter-HPM application space. However, modulating the electrical conductivity (i.e., the imaginary component of permittivity) of a solid is a path toward overcoming limitations pertaining to center frequency, bandwidth, and AOI.
