1. Wave Splitting in Direct and Inverse Scattering Problems
Sammanfattning : The focus of this thesis is on the use of wave splitting in electromagnetic direct and inverse scattering problems. Wave splitting offers a decomposition of wave fields into appropriate input and output wave constituents. LÄS MER
2. Computational Methods and Measurements for Direct and Inverse Scattering of Microwaves
Sammanfattning : Electromagnetic waves are widely used in society today for a multitude of applications. Design of electromagnetic devices and applications requires accurate methods for evaluating performance, which often means modern computational methods. LÄS MER
3. Scattering on the Timoshenko Beam. Direct and Inverse Problems in the Time Domain
Sammanfattning : This thesis concerns the use of time domain methods for treating direct and inverse scattering problems for flexural waves on beams. The Timoshenko equation is used throughout to describe the behaviour of such waves. LÄS MER
4. Direct and Inverse Methods for Waveguides and Scattering Problems in the Time Domain
Sammanfattning : Numerical simulation is an important tool in understanding the electromagnetic field and how it interacts with the environment. Different topics for time-domain finite-difference (FDTD) and finite-element (FETD) methods for Maxwell's equations are treated in this thesis. LÄS MER
5. Direct and Inverse Scattering of Electromagnetic Waves in Nonlinear Media
Sammanfattning : Models for materials with nonlinear electromagnetic response are examined. Three simple physical causes for nonlinear behavior are presented: electronic polarization, molecular direction and electrostriction. LÄS MER
