Estimating Near-Field Signals Emanated by Embedded Systems Using Data-Dependent EM Profiles as Basis Functions

An efficient modeling approach to synthesize near-field EM signals radiated from a general-purpose micro-controller is proposed. The method assumes that near-field signals for on-chip data computations can be generated using a linear combination of basis functions, constructed using data-dependent EM profiles that correspond to vectors in a binary vector space.
