Patent ID: 7991570

Claim:
A method for reconstructing a signal of interest, comprising: producing a collection of Poynting vectors by: collecting magnetic-field data along three orthogonal axes, wherein said magnetic-field data is collected with a tri-axial B-field sensor; collecting electric-field data along three orthogonal axes, wherein said electric-field data is collected with a tri-axial E-field sensor; digitizing said magnetic-field data and said electrical-field data to produce digitized data; producing calculated E-field components and B-field components from said digitized data; and calculating said collection of Poynting vectors from said calculated E-field components and B-field components; the method further comprising: identifying, from said collection of Poynting vectors, spectral peaks having a common Poynting vector, to produce a set of commonly oriented Poynting vectors; and reconstructing a signal of interest from said set of commonly oriented Poynting vectors.
