   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

3. 2. Time-Domain Inverse Electromagnetic Scattering using FDTD and Gradient-based Minimization

   Författare :Erik Abenius; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; inverse scattering fdtd minimization adjoint ;

   Sammanfattning : The thesis addresses time-domain inverse electromagneticscattering for determining unknown characteristics of an objectfrom observations of the scattered .eld. Applications includenon-destructive characterization of media and optimization ofmaterial properties, for example the design of radar absorbingmaterials. LÄS MER
