Theory of characteristic modesThis article presents a method of using modal analysis to characterize the circular polarization (CP) performance of a printed monopole antenna. The radiator and feedline are positioned on the edge of the substrate and fed accordingly at the edge, and a modified ...

We will now explain that the characteristic property of a surface defect localized in the z2 direction is that it gives a bimodule BϵD1,ϵ2 with some kind of weight condition. Classically, we need to look at the action of the gauge Lie algebra Diffϵ2 on the surface C defect ...
(1991), and dressed polarizability approaches of Yoo and Park (2012). These approaches offer similar simplicity of using Mie theory in conjunction with an effective medium theory, but offer a more rigorous treatment of the coupled optical response of the spherical particle to its neighbors.

Fig. 6b demonstrates the effect of constrained warping on the natural frequencies of a bending-torsion coupled graphite-epoxy I-beam. It can be observed that constrained warping increases the natural frequencies of torsion-related modes via an increase in torsional stiffness; the increase is larger ...
These modes are coupled by the interband electron-electron interaction, and we consider the effect of impurity scattering on this coupling mechanism. The paper is written as follows. We start with the derivation of a system of Bethe-Salpeter (BS) equations con- taining coupled SDW and Cooper...
This is the secondresearch gapaddressed by the present work, which consists of applying analytical methods to the indices linked to the rankings that allow for identifying the characteristic features that define the cities. The traditional approach to smart city rankings simplifies the choice of the ...
