Below is my presentation for today.

I’ve come down to the end and all I have left to do is write. This presentation gives a good summary of why I am doing it, what I have done, and where I have to stop. The conclusion: non-trivial problems are too complex for analytical solutions, full geometry 3d numerical modeling is needed. If each slot was individually excited this problem would have been finished, but since they are all excited by one source that gives rise to eddy currents to drive the slots they become mutually coupled in a non trivial way.

Either case great learning experience on the Equivalence principle, limits of Born’s first approximation and dyadic Green’s functions. All and all, I’m proud of my work.

All done in Latex with the beamer class.

Below is my presentation for today. It sums up where I am with the rectangular and cylindrical version of the problem and the steps to go about solving it.

Future work includes the mutual coupling of slot antenna arrays which should bring me to the end of the thesis (after optimization).

So being a member of Sigma Xi every year I get to present some work that I have been doing to members of Marquette’s Sigma Xi. A good mixture of students and teachers are there.

This is my master’s thesis up to this date.

So it seems my last post was a little premature. I haven’t gotten the correct answer yet but I’ve been working on some stuff that will get me there. I think I can get the single slot application working in the next week or so. And again, I will probably be so happy that I will blog about the results. eesh

Below is my presentation for today. It sums up a rectangular version of the problem and the steps to go about solving my problem. Hopefully my next presentation at the end of the semester will be a completed thesis.

Here is a report that I wrote for my numerical analysis course at Marquette University.

Right now the code solves an arbitrary 2-d waveguide geometry for its k value. The code uses an eigenmode solution and should be rather easy to implement the eigenvector solution and print it out on gmesh.
