Focused high frequency electromagnetic waves reflected from a PEC paraboloidal surface placed in homogeneous, reciprocal and isotropic medium with chirality parameter are analyzed.The value of the is set such that it simultaneously supports modes negative positive phase velocities.Present work an extension previous work, which chiral only velocity.Using derived expressions, line plots focal region obtained.
