is it possible for an object to have product of relative permittivity & permeability < 1

velocity of light in a medium is given by

v = (1/00)^1/2

where one epsilon & mu are for absolute value & anuther for relative value.

putting value of 00,

v = c/()^1/2

if product of these two are less than one, velocity in that medium 'll be more than velocity of light.

so please say is it possible that =1.5 & = 0.5 for a particular medium.
