We demonstrate that the electromagnetic fields scattered by particles made of\ndifferent materials can be equalized. Emphasize is placed first in metallic\nnanoparticles that host localized surface plasmons and it is shown that their\nelectromagnetic fields can be identically reproduced with dielectric particles.\nWe derive the explicit formulas relating the different constitutive parameters\nthat yield identical electromagnetic responses. This method provides the\ndielectric permittivities of spherical particles that reproduce the strong near\nelectric field intensities observed around metallic particles featuring\nlocalized surface plasmon resonances in optics or near infrared frequencies. We\nalso demonstrate the ability of homogenous dielectric particles to host the\nmagnetic resonances predicted for exotic materials with negative permeability.\n
