<p>To whom it may concern,</p>
<p><br /></p>
<p>I was interest in using GetDP to solve for the eigenfrequencies and corresponding eigenvectors for arbitrary 2D waveguide cross-sections containing one or more mixed dielectrics defined by complex permittivities and permeabilities to add loss to the solution? This topic is not addressed in the GetDP User Guide, where only relative permittivity is mentioned and complex permeability is mentioned for metal cores. </p>
<p><br /></p>
<p>Next, adaptive mesh refinement is mentioned on p. 30 of the gmsh User Manual, but is not mentioned elsewhere in the document. Can gmsh be used to continually refine the mesh to solve for higher order normal modes of a waveguide cross-section? If so, how is this implement?</p>
