Calculating Magnetic Permeability Response of a Conducting Square Ring Structure
In the present work, we investigate the tunability of the magnetic response of a new structure. A lattice of periodically arranged close-packed square conducting rings has been studied for this purpose. Here, instead of enhancing the magnetic activity via resonance, like in split-ring resonators, we concentrate on the analysis of the interactions between these rings. The core idea is to design ...
متن کاملT he square Fibonacci tiling *
We introduce the 2-dimensional square Fibonacci tiling and its generalization to higher dimensions as models for quasicrystals without ‘forbidden’ symmetries. We derive some of the basic mathematical properties of the tiling as well as calculate its diffraction pattern. We discuss the relevance of the Fibonacci tiling for quasicrystal research and for applications in other fields. 2002 Elsevi...
متن کاملT-cell magnetic drive.
Adoptive T-cell transfer is a cancer immunotherapy strategy that involves extraction of T cells from a patient, ex vivo expansion and activation, and reinfusion in the body for tumour targeting. During the ex vivo treatment, T cells are trained to recognize cancer biomarkers on exposure to antigen-presenting cells (APC), which reprogrammes them into antigen-specific cytotoxic T cells (CTLs) for...
متن کاملCompact Artificial Magnetic Conductor Designs Using Planar Square Spiral Geometries
Compact spiral artificial magnetic conductors (AMC) have been investigated in this paper. First, single and double spirals are examined to achieve an in-phase reflection at a lower frequency compared to a conventional patch element of the same size. However, these two designs generate a large cross polarization. The cross polarization affects the operating frequency and bandwidth. In order to e...
متن کاملThermally induced magnetic relaxation in square artificial spin ice
The properties of natural and artificial assemblies of interacting elements, ranging from Quarks to Galaxies, are at the heart of Physics. The collective response and dynamics of such assemblies are dictated by the intrinsic dynamical properties of the building blocks, the nature of their interactions and topological constraints. Here we report on the relaxation dynamics of the magnetization of...
