    Retrieving the refractive index

    Hi RRumpf, Your lecture notes are simply beautiful. Thanks for the effort. Can you also include your simulation examples (CST or whatever) and your Matlab code for effective parameter retrieval? This would be a tremendous help. Thanks.

    CST Simulation: Local Density of Optical States LDOS

    This is a helpful paper for something like a photonic crystal, but I would like to calculate the LDOS for an arbitrary structure. An arbitrary structure could include a resonant dielectric sphere, a waveguide, or anything of that nature.... something that isn't periodic and preferably lossy to...

    Problem with linking between Matlab, CST and applying Genetic Algorithm(GA)

    Does anyone know how to run a CST macro from Matlab? Also, how do you get the results from the result tree using Matlab?

    Retrieve the effective parameters of metamaterial

    It's important to note that there is a branching ambiguity due to the arc cosine function. This issue causes some regions in the calculated spectrum, for the real part of the refractive index, to have the wrong sign or amplitude. As a result, these regions require correction by hand. The...

    How to determine the effective thickness of metamaterial

    This method doesn't require an effective metamaterial thickness calculation for the calculation of the effective parameters. Also, code is provided online for the algorithm (see references in paper). A Unique Extraction of Metamaterial Parameters Based on Kramers–Kronig Relationship Zsolt...

    How do I automate or create a script in CST to postprocess some CST s-parameters?

    Anyone know how to extract the Q-Value from the \Tables\0D Results\ folder? I use Q1=invoke(mws, 'SelectTreeItem','Tables\0D Results\Q-Value-h-field (f=resf)') but it does not give me the q-value that is calculated from the simulation. I get Q1 = 1. Please help.
