Abstract = {{Compact samples of nano-helices built by means of a focused ion beam
   technology with large bandwidth and high dichroism for circular
   polarization are promising for the construction of built-in-chip
   sensors, where the ideal transducer must be sufficiently confined
   without compromising its filtering ability. Direct all-optical
   measurements revealed the sample's dichroic character with insufficient
   details because of scattering and diffraction interference. On the other
   hand, photoacoustic measurements resulted to be a possible alternative
   investigation, since they directly deal with absorbed power and allow to
   get clear evidences of the differential selection for the two opposite
   polarization states. Multilevel numerical simulations confirmed the
   experimental results, proving once again the reliability of
   photoacoustic technique and the versatility of this class of dichroic
   artificial materials.}},
