[1] A discussion on the physical realizability of electromagnetic wave absorbers with perfectly matched impedances over arbitrary (i.e., doubly) curved, smooth surfaces is presented. The focus is on the analysis of the spectral characteristics (and their impact on the absorptive properties) of hypothetical material blueprints derived from the zeroreflection condition over such geometries.

In this paper, the Multi-Section Transformers (MSTs), the lengths of whose sections are not the same, are proposed and considered as matchers between two complex and frequency dependent impedances in a wide frequency range. The optimum values of the MST parameters are obtained through optimization approach. The usefulness of the proposed structure is verified using some examples.

This paper presents a real-time algorithm that allows robust tracking of multiple objects in complex environments. Foreground pixels are detected using luminance contrast and grouped into blobs. Blobs from two consecutive frames are matched creating the matching matrices. Tracking is performed using direct and inverse matching matrices. This method successfully solves blobs merging and splittin...

This paper examines the effects of education on intermarriage, and specifically whether the mechanisms through which education affects intermarriage differ by immigrant generation, age at arrival, and race. We consider three main paths through which education affects marriage choice. First, educated people may be better able to adapt to different cultures making them more likely to marry outsid...

We show theoretically that a finite two-dimensional square lattice of metallic cylinders in air can be designed to have almost 100% absorptance over a wide optical wavelength range and for a wide range of incidence angles. The broadband and wide-angle strong absorption is attributed to the presence of a large number of flat bands interacting with air bands and the greatly improved impedance mat...
