Kwan's PIT Project
Modeling EM waves using cellular automata
Can cellular automata models be used to analyze EM propagation behaviors in building with multipath propagations? I would like to understand how much wireless data rate dense radio environments could support. I am considering an area like the Media Lab cube where every single item in the area has an RF connection with people carrying around devices like mobile phones that may also relay RF signals. I would like to understand how EM waves behave and propagate in such environments by modeling them in numerical simulators. Such invesgtigation will allow how much data rate can be consistently supported in such environments and what kind of multiple access mechanism could be used for all the distributed radios to constantly communicate with each other.
For the PIT class, my goal is to understand how EM modeling works and build a simple cellular automata based EM modeler that can model simple EM waves and dipoles.
Understand how FDTD and LGA models work
