ADI-MRTD Algorithm for Periodic Structures Analysis

Mrtd Electromagnetic Scattering Analysis

In this paper, we ha e de eloped a multiresolution time( ) ( ) domain MRTD scheme to analyze two-dimensional 2-D scattering objects with comparison to the corresponding finite-difference time( ) domain FDTD method. We ha e applied an anisotropic perfectly ( ) matched layer APML absorber for open boundary truncation in the content of the MRTD scattering analysis. In addition, we ha e constructed...

Complementary Periodic Structures for Miniaturization of Planar Antennas

In this paper various layered planar periodic structures which provide miniaturization of planar antennas are proposed and discussed. The proposed designs are based on two concepts, reactive impedance surfaces and complementary periodic structures. In the proposed structures, complementary periodic rings and slots are patterned on the intermediate boundaries of the dielectric layers. A patch an...

ADI-Minebio: A Graph Mining Algorithm for Biomedical Data

Graph mining is concerned with mining frequent subgraph patterns over a collection of graphs, aiming to find novel and useful knowledge. It has being used to analyze data from different domains, sometimes using algorithms tailored for a specific area of knowledge. In this article, we propose a graph-mining algorithm and its application in the biomedical domain. We introduce the following contri...

An inverse-free ADI algorithm for computing Lagrangian invariant subspaces

The numerical computation of Lagrangian invariant subspaces of large scale Hamiltonian matrices is discussed in the context of the solution of Lyapunov and Riccati equations. A new version of the low-rank alternating direction implicit method is introduced, which in order to avoid numerical difficulties with solutions that are of very large norm, uses an inverse-free representation of the subsp...
