Research opportunities exist in the area of high-gain and multibeam antennas to support Air Force air- and spaceborne radar systems. We are particularly interested in wideband (>1 octave) and multiband systems, and in developing both new antenna designs and new efficient analysis methods. This applies to directly radiating planar and conformal arrays, as well as array-fed reflector and lens configurations, which offer the potential for an electrically scanned, high-gain beam at low cost.
Other topics of interest include wide-scan wideband planar arrays, arrays for hemispherical coverage, low-profile UHF/VHF arrays on conformal platforms, planar and conformal frequency selective surfaces, efficient electrically small antennas, and applications of metamaterials in novel antenna and lens designs.
A final topic centers on computational electromagnetics for electrically large bodies. We need to improve both frequency and time domain methods, which eventually will permit us to numerically analyze large finite planar and conformal arrays, including mutual coupling and edge effects on large complex platforms, possibly of exotic nonconducting materials including metamaterials.
