DESCRIPTION:Disordered hyperuniform materials are an emerging class of amo
 rphous statesof matter that are endowed with novel wave and transport char
 acteristics with advantages over their periodic counterparts. Such materia
 ls are characterized by an anomalous suppression of infinite-wavelength de
 nsity fluctuations relative to those in typical disordered systems.An impo
 rtant class of such hyperuniform materials are the disordered "stealthy'' 
 varietiesin which there is no single scattering from intermediate to infin
 ite wavelengths.I will briefly review the hyperuniformity concept. Then I 
 will describerecent work on some extraordinary electromagnetic wave progag
 ation propertiesof disordered stealthy hyperuniform dielectric composites 
 withvarious structural symmetries.
