The product composition control in a multicomponent distillation column presents several challenges in the industry. The development of a soft sensor enables the monitoring of the product quality using an inferential model and on-line measured proces

WOS:000341980900022 (Nº de Acesso Web of Science) We develop a generalized image method to solve radiation problems in nonreciprocal stratified Tellegen media. It is shown that the electromagnetic fields emitted by elementary sources have exact anal

In this article the in∞uence of both dispersion and losses on waveguides with metamaterials is investigated. The analysis is focused on surface waveguides (planar interfaces and grounded slabs) containing either double-negative (DNG) or chiral meta

Using a building block approach which combines a transverse resonance method with a mode-matching technique, a rigorous analysis of a lossless bi-isotropic H-guide is presented. First, the modal equation of a parallel-plate waveguide containing the i

Guided-wave propagation in chiral H-guides is analyzed, using a building-block approach. In a flrst stage, a 2D chiral parallel-plate waveguide is studied using a lossless frequency dispersion model for the optically active medium, where the constitu

This paper addresses the guided-wave propagation in an open uniaxial ridge waveguide. The analysis is focused on the discrete modes, although including both guidance and leakage behavior. It is shown that, beyond a certain critical frequency, the sur

As already pointed out by several authors, a given electromagnetic medium creates an effective geometry and a given geometry creates an effective medium—what we call the equivalence principle for electromagnetics. This bears some resemblance to the

Surface and proper leaky modes guided by a grounded pseudochiral omega slab are studied. A new physical result is found: proper leaky modes may occur in a lossless grounded pseudochiral omega slab even when all medium parameters are positive. A corre
