Near-field estimation using a reduced basis expansion of induced modes in a human head model from equivalent sources

A new approach to evaluate near-field induced by a cellular phone in a human head model using an E-field expansion into a basis is proposed. This technique is first based on Huygens principle using equivalent currents on a closed surface which makes it valid for any cellular phone. Then, using Singular Value Decomposition, the generated induced E-field by any cellular phones would be expanded with the orthonormalized modes excited by the equivalent sources in a human head model. Finally, we estimate the error reconstruction of E-field using a reduced number of modes.
