Jason Sidabras

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).

With this post, I become one step away from being getting the Holy Grail of my Master’s Thesis. With the help of Pozar and Pan’s papers on mutual coupling of slot antenna arrays, it looks like finishing this master’s thesis will all of the things I wanted to do isn’t that far fetched.

So what am I so happy about?

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.
