Mode Transfigurations in Chirowaveguides
it has been analyzed physical features of the modes behavior in a waveguide filled with the chiral medium. Both mathematical and physical models of their propagation have been defined and modes classification has been suggested. It has been shown that the same root feature in dispersion is typical both for chirowaveguide modes and for the unchiral waveguide; however the mode transfiguration is ...
متن کاملDiscontinuities in Planar Chirowaveguides
In this paper, we propose, develop, and implement an exact method to analyze the effect of discontinuities in open planar chirowaveguides. The method combines the buildingblock approach of multimode network theory with a rigorous mode-matching procedure. Both the scattering of discrete spectra surface-wave modes and the continuous spectra radiation and evanescent modes are discussed in this pap...
متن کاملOn Approximate Birkhoff-James Orthogonality and Approximate $ast$-orthogonality in $C^ast$-algebras
We offer a new definition of $varepsilon$-orthogonality in normed spaces, and we try to explain some properties of which. Also we introduce some types of $varepsilon$-orthogonality in an arbitrary $C^ast$-algebra $mathcal{A}$, as a Hilbert $C^ast$-module over itself, and investigate some of its properties in such spaces. We state some results relating range-kernel orthogonality in $C^*$-algebras.
متن کاملGlobal Orthogonality Implies Local Almost-orthogonality
We introduce a new stopping-time argument, adapted to handle linear sums of noncompactly-supported functions that satisfy fairly weak decay, smoothness, and cancellation conditions. We use the argument to obtain a new Littlewood-Paley-type result for such sums. 0. Introduction. First, an apology. The title, though correct, is somewhat misleading. It should be “Global almostorthogonality implies...
متن کاملOrthogonality breaking induces extraordinary single-mode transparency in an elaborate waveguide with wall corrugations
Orthogonality plays a fundamental role in various mathematical theorems and in physics. The orthogonal eigenfunctions that represent the intrinsic motions of various physical systems can also be regarded as transverse wave modes in a straight waveguide. Because of their orthogonality, these modes propagate independently, without mutual interference. When the wall separation fluctuates, the form...
