MWSW04 - Multiple scattering in engineering and applied sciences

Disordered hyperuniform materials are an emerging class of amorphous statesof matter that are endowed with novel wave and transport characteristics with advantages over their periodic counterparts. Such materials are characterized by an anomalous suppression of infinite-wavelength density fluctuations relative to those in typical disordered systems.An important class of such hyperuniform materials are the disordered “stealthy’’ varietiesin which there is no single scattering from intermediate to infinite wavelengths.I will briefly review the hyperuniformity concept. Then I will describerecent work on some extraordinary electromagnetic wave progagation propertiesof disordered stealthy hyperuniform dielectric composites withvarious structural symmetries.
