Orthogonality Properties of Characteristic Modes for Lossy Structures

چکیده
Orthogonality of the characteristic modes with respect to weight operator generalized eigenvalue equation (GEE), and in far-field, is investigated case lossy conducting dielectric objects. Linking radiated power shown provide orthogonal far fields lossless case. In case, both orthogonality modal currents are satisfied Hermitian inner products only for sufficiently symmetric geometries, such as a sphere. For irregular shapes, independent symmetry formulation, far-field can be obtained (non-Hermitian) product. The (complex) formulations, but again Since not related any physical quantity, do form (radiated) set Hence, structures, (CMs) satisfy their classical definition they need redefined.

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
On the Characteristic of Orthogonality for Multi-Carrier-Based Systems
The dominate factors caused by reasons of losing the orthogonality in fading channel including FBC (fading branch correlation), CFO (carrier frequency offset), and even the CPN (carrier phase noise) are novel discussion in this letter. The first one factor causes the ISI (inter-symbol interference), and, however, the latter two will lead to the phenomenon of CPE (common phase error) and ICI (in...

CHARACTERISTIC FUNCTIONS AND s-ORTHOGONALITY PROPERTIES OF CHEBYSHEV POLYNOMIALS OF THIRD AND FOURTH KIND
The properties of two families of s-orthogonal polynomials, which are connected with Chebyshev polynomials of third and fourth kind, are studied. Evaluations of the remainders are given and asymptotic formulae are calculated for the corresponding hyper-Gaussian formulae used for an approximate estimation of integrals. 2000 Mathematics Subject Classification: 33C45, 65D32.
