Focusing of electromagnetic plane wave from a large size paraboloidalreflector, composed of layers of chiral and/or chiral nihility metamaterials,has been studied us- ing Maslov's method. First, the transmission andreflection of electromagnetic plane wave from two parallel layers of chiraland/or chiral nihility metamaterials are cal- culated using transfer matrixmethod. The effects of change of angle of incidence, chirality parameters andimpedances of layers are noted and discussed. Special cases by taking verylarge and small values of permittivity of second layer, while assuming value ofcorresponding chirality equal to zero, are also treated. These special casesare equivalent to reflection from a perfect electric conductor backed chirallayer and nihility backed chiral layer, respectively. Results of reflectionfrom parallel layers have been utilized to study focusing from a large sizeparaboloidal reflector. The present study, on focusing from a paraboloidalre{\deg}ector, not only unifies several published works conducted by differentresearchers but also provides better understanding of new cases.
