Hey guys, first time here... 1. The problem statement, all variables and given/known data I have to write an essay crtitiquing the various methods of EM modelling with regards to the specific situation of investigating the EM fields in the vicinity of houses in a town 2km froma Radar Tower. The problem does not have to be solved, and there are no specifics; rather an analysis of the various methods of EM modelling is required with a precis of how one would implement them. Main methods covered are Finite Element Analysis, Method of Moments, and Finite Difference Time Domain. The radar is for maritime survey and local air traffic, which can be a frequency of 1-8 GHz, or wavelength of 2.5 - 15cm. 2. Relevant equations No actual modelling is required 3. The attempt at a solution FDTM would be useful for modelling the a simplification of the town as an entity (i.e. a bunch of cuboids) since the rough dimensions of the town and a height of 2 stories would suffice as boundaries. The house shapes can be rough because their dimensions are of a much higher order than the wavelength of the radar. For the internals of the house, FEM would be best since the space in the house is being meshed rather than the objects, the system is closed so there is no need to worry about the field at infinity, and obviously at a scale of 3-15cm the objects in a house are inhomogeneous. Thats the guts of my solution, without going into why the other methods aren't good etc. Have I missed anything or got anything majorly wrong? Thanks.
