Description
Summary:Recently, a significant effort from different research groups have been aimed at the problem of reconstructing the extreme near field radiated by an antenna from measured field data [1]-[8]. Among the different proposed solutions, the inverse source or equivalent current/source method (EQC) based on discretization of integral equations has attracted considerable attention due to a host of promising applications in antenna design and diagnostics. The integral equation approach constitutes a complement to more established tools such as plane-wave or spherical-wave expansion. At the expense of heavier computational burden this method offers a greater generality and flexibility since it allows reconstructing sources on arbitrary 3-D surfaces enclosing the antenna under test (AUT).
