Our goal is to develop systems simulations capabilities based on time-domain computational electromagnetics methods.  This ambitious goal gives the design engineers the ability to simulate pieces of or entire systems for electromagnetic interactions.  In order to achieve the goal, several fundamentals, which inherently provide or deny any capabilities the eventual simulation tools will have, must be considered: 
 

	The electromagnetics theory (time-domain, frequency-domain, frequency-dependent, et cetera) essentially dictates the possible capabilities of the electromagnetics algorithm.
	The programming theory and algorithm (C, FORTRAN, C++, serial, parallel, MPI, threads, hard-coded, static versus dynamic task assignment, et cetera) essentially dictate the possible capabilities of the electromagnetics algorithm and the final simulations code.
	The hardware (disks, disk access methods in code, networking to disks, disk file systems, CPU architecture, cache size/hierarchy, memory size/hierarchy, et cetera) which must eventually perform the computations strongly influences each of the aforementioned concerns and must be addressed during development as an integral design component.

CEM TACH emphasizes the nature of our group which is grounded in Theory, Algorithm, Code and Hardware development directed towards creating very capable, very general and very fast simulation tools.
