Proceedings Article
Solar cell stacked modified Z-double L-slot quad-band PIFA
TL;DR: In this article, a low-profile quad-band multifunctional solar PIFA consisting of a polycrystalline silicon (poly-Si) solar cell stacked suspended modified radiating element with Z and double L-slots was proposed.
Journal ArticleDOI
Spatial coherence in 2D holography.
TL;DR: Incoherent illumination is shown to result in more robust imaging performance free of diffraction artifacts at the cost of incurring background noise and sacrificing phase retrieval, and numerical studies confirm that this background noise reduces image sensitivity as the image size increases, in agreement with other similar systems.
Journal ArticleDOI
Mode diversity of weakly modulated cavity antennas.
Daniel L. Marks,David R. Smith +1 more
TL;DR: Using time-independent perturbation theory, the modes of a cavity perturbed by many modulating elements are derived and it is found that with a sufficient number of modulators of sufficient strength, the number of unique fields radiated by the cavity may reach a limit determined by the numberof unperturbed cavity modes.
Journal ArticleDOI

Quasi-Conformal Approaches for Two and Three-Dimensional Transformation Optical Media
TL;DR: The authors examined the quasi-conformal method as it applies to transformation optics and showed that while it does significantly ease the burden of material design and fabrication, it may also create severely aberrant behavior unless caution is taken.
