optimization
Opis:: A gradient based optimization technique along with a new definition of cost function is applied to synthesis of coupled resonators filters. The cost function is defined using location of zeros and poles of the filter's transfer function. The topology of the structure is enforced on each step of optimization and its physical dimensions are used as independent variables.

Tytuł:: Mesh-free approach to Helmholtz equation based on radial basis functions
Autorzy:: Kowalczyk, P.
Mrozowski, M.
Powiązania:: https://bibliotekanauki.pl/articles/309385.pdf
Data publikacji:: 2005
Wydawca:: Instytut Łączności - Państwowy Instytut Badawczy
Tematy:: Helmholtz equation
radial basis functions
meshfree method
cylindrical waveguides
Opis:: Recently, a radial basis functions (RBFs) method, which was originally proposed for interpolation problems, has been developed and applied to solve partial differential equations and eigenproblems. Properties of that method (meshfree algorithm) allows one to use it in many areas, including electromagnetics. In this paper the mesh-free RBF method for solving Helmholtz equation was applied and a new adaptive algorithm for defining the set of interpolation centers was proposed. Using the proposed approach the cutoff wavelengths and the field distribution in cylindrical waveguides of arbitrary cross-section were calculated with a high accuracy.
