Modelling electromagnetic field sensors

Abstract

Sensors may use the attenuation, velocity and electrical dispersion of electromagnetic waves as a direct or intermediate step in the transduction process. Modelling the sensor response provides the means to predict its spatial and temporal sensitivity and accuracy. The modelling may use differential or integral equation techniques. Each method has situations where its advantages dominate. As an example, a typical integral equation solution is described, along with discussion of cell size and shape considerations and selection of an appropriate basis function. © 2008 Springer-Verlag Berlin Heidelberg.
