heal.abstract	According to recent works, when one applies the method of auxiliary sources (MAS) to scattering problems, it is possible for the MAS currents to be strongly oscillatory. For two simple geometries, the ""cylindrical"" and ""planar"" problems, we study the near field generated by these oscillatory currents analytically and numerically and point out analogies to the near fields of superdirective antennas. For both geometries, the source is an infinitely long electric current filament while the respective scatterers are an infinitely long perfect electric conductor (PEC) circular cylinder, and an infinite PEC planar ground plane. © 2012 IEEE.	en
