I want to know about zero refractive index materials. How can we draw a zero refractive index surface above microstrip patch antenna with CLR and SRR structures.
Dear Divyanshu Upadyay,
I do not have experience in HFSS, but in general, any EM software will let you define an isotropic material with specific values of permittivity and permeability. If this is not possible, there is always a Drude or Lorentz function that can be used to create a negative index material for an specific frequency.
You can get an artificial material with zero refractive index with CLR or SRR. But notice that such artificial material will not be isotropic.

Zero refractive index means, no refraction of a wave while travelling through media. No refraction is possible only, if, plane wave travelling in a pure homogeneous material. In other word material characteristic does not get changed within the media under consideration. In a sense every homogeneous material has a zero refractive index
Thanks...@Amipara Manilal... Have u any idea about refractive index vs frequency plot in HFSS?
