Anisotropic circular topological structures
نویسندگان
چکیده
We design cylindrical multilayer structures characterized by anisotropy and topological features. This provides a new approach to tailor electromagnetic fields into desired patterns with orbital angular momentum in geometries as ring resonators fibers. use transformation optics deal anisotropic circular structures, rigorously define the edge states. The resulting topologically protected high-localized modes, at core/cladding interface, may trigger developments of disorder-robust devices high Q-microcavities for applications light transmission, quantum technology, nonlinear optics, TeraHertz devices, biophysical sensors.

Diffraction theory of an anisotropic circular cylinder.
A fully analytical theory is developed to derive the field diffracted by an infinitely long circular cylinder made of an arbitrary anisotropic homogeneous material, illuminated by an arbitrary plane wave.
متن کاملThe topological derivative in anisotropic elasticity
A comprehensive treatment of the topological derivative for anisotropic elasticity is presented, with both the background material and the trial small inhomogeneity assumed to have arbitrary anisotropic elastic properties. A formula for the topological derivative of any cost functional defined in terms of regular volume or surface densities depending on the displacement is established, by combi...
متن کاملExtraction of Topological Structures
Analyzing large and high-dimensional flow data sets is a non-trivial task and favorably carried out using sophisticated tools which allow to concentrate on the most relevant information and to automate the analysis. These goals can be achieved using topological methods, which foster target-oriented studies of the most important flow features. They have a variety of applications which ranges fro...
متن کاملOn Random Topological Structures
and Applied Analysis 3 As a result of 2.2 we obtain, for each x, y ∈ 0, 1 , T ( x, y ) ≤ T x, 1 x, T ( x, y ) ≤ T ( 1, y ) y. 2.5 Since, for all x, y ∈ 0, 1 , trivially T x, y ≥ 0 TD x, y , we get for an arbitrary t-norm T , TD ≤ T ≤ TM. 2.6 That is, TD is weaker and TM is stronger than any other t-norms. Also since TL < TP , we obtain the following ordering for four basic t-norms TD < TL < TP ...
متن کاملOrdered Topological Structures
The paper discusses interactions between order and topology on a given set which do not presuppose any separation conditions for either of the two structures, but which lead to the existing notions established by Nachbin in more special situations. We pursue this discussion at the much more general level of lax algebras, so that our categories do not concern just ordered topological spaces, but...
