A procedure for evaluating RF electromagnetic fields in
anatomical human models for any matching and coupling
conditions is introduced. The procedure resorts to the
extraction of basis functions: such basis functions,
which represent the fields produced by each individual
port without any residual coupling, are derived through
an algebraic procedure which uses the S parameter matrix
and the fields calculated in one (only) full-wave
simulation. The basis functions are then used as
building-blocks for calculating the fields for any other
S parameter matrix.
