We quantize the Maxwell Chern Simons theory in a geometric representation that generalizes the Abelian Loop Representation of Maxwell theory. We find that in the physical sector, the model can be seen as the theory of a massles scalar field with a topological interaction that enforces the wave functional to be multivalued. This feature allows to relate the Maxwell Chern Simons theory with the q...

This paper aims to show that making use of Newton’s view on equations of motion of a physical system and of the Maxwell stress tensor we come to a natural nonlinearization of Maxwell equations in vacuum making use only of nonrelativistic terms. The new equations include all Maxwell solutions plus new ones, among which one may find time-stable and spatially finite ones with photon-like propertie...

We present solution generating methods which allow to construct exact static solutions to the equations of four-dimensional Einstein-Maxwell-Dilaton gravity starting with arbitrary static solutions to the pure vacuum Einstein equations, Einstein-dilaton or Einstein-Maxwell equations. In four dimensions the field equations of the Einstein-Maxwell-dilaton gravity with arbitrary dilaton coupling p...

En el área de las comunicaciones móviles, el álgebra de cuaterniones fue aplicada al estudio de las ecuaciones de Maxwell (descripción de los aspectos de propagación de las ondas electromagnéticas) ya desde los trabajos del mismo Maxwell. Por lo tanto, no resulta extraño que una gran parte de los trabajos científicos modernos utilicen este tipo de técnicas en la resolución del sistema de Maxwel...

We prove that the electromagnetic material parameters are uniquely determined by boundary measurements for the time-harmonic Maxwell equations in certain anisotropic settings. We give a uniqueness result in the inverse problem for Maxwell equations on an admissible Riemannian manifold, and a uniqueness result for Maxwell equations in Euclidean space with admissible matrix coefficients. The proo...

The Substrate Integrated Waveguide (SIW) technology is an attractive approach for the design of high performance microwave and millimeter wave components, as it combines the advantages of planar technology, such as low fabrication costs, with the low loss inherent to the waveguide solution. In this study, a substrate integrated waveguide power divider, circulator and coupler are conceived and o...

A probe-fed circularly polarized 3-layer stacked patch antenna is presented and simulated by using Commercial Ansoft High Frequency Structure Simulator. The design consists of three patches and three substrates. The lower and middle patches are of square-shaped where as the upper patch is of triangular-shaped. One slot is inserted in the lower layer, two slots are inserted in the middle layer a...

As wireless communication applications require more and more bandwidth, the demand for wideband antennas increases as well. For instance, the ultra wideband radio (UWB) utilizes the frequency band of 3.1–10.6GHz.This paper presents a work carried out within ULTRAWAVES in the area of antenna design and analysis. A new multilayer microstrip antenna is introduced using Stacked Multiresonator patch...

A broadband MEMS steerable antenna is fabricated on a silicon substrate using bulk micromachining techniques. The MEMS platform utilizes torsion hinges and is capable of rotation around two axes for full beam steering capabilities. The antenna was designed using the Ansoft High Frequency Structure Simulator (HFSS) package and operates between 10-16 GHz with a coplanar feedline routed across the...
