摘      要：We present a novel method for designing transformation optical devices based on *** arbi-trary transformation of electrostatic field can lead to a new refractive index distribution,where wave-fronts and energy flux lines correspond to equipotential surfaces and electrostatic flux lines,*** to scalar wave propagating exactly following an eikonal equation,wave optics and geometric optics share the same solutions in the *** method is utilized to design multipole lenses derived from multipoles in *** source and drain in optics are considered as corre-sponding to positive charge and negative charge in the static *** defining winding numbers in vir-tual and physical spaces,we explain the reason for some multipole lenses with illusion ***,we introduce an equipotential absorber to replace the drain to correspond to a negative charge with a grounded ***,it is a very general platform to design intriguing devices based on the combination of electrostatics and transformation optics.
