There are so many papers where they select different materials for forming metamaterial also use different substrates as well as liquids that evaporate. What interests me most is which materials show the best result to form metamaterials that can be used for nanoantennas. Thus I want to know what to select for forming metamaterials.
The choice of material depends on the type of use of this material. For what purpose are these materials used? In sensing or absorption or detection?
Saad Zahraw Sekhi I want to use the designed metamaterial to build some nanoantenna.
Some of the materials are listed below for your help.
a) Niobium as Alternative Material for Refractory and Active Plasmonics
b) Hybridized Plasmonic Gap Mode of Gold Nanorod on Mirror Nanoantenna
c) ferromagnetic metals such as nickel, cobalt, iron or their alloys for magneto-plasmonic nanoantennas
All metals, doped Semiconductors, doped oxides can give you plasmonic effects.
The Question is what frequency range to choose the proper material.
Silver, Gold and Aluminium is considered as best material for plasmonic nanoantennas
Saad Zahraw Sekhi thank you so much for your answer. It is very insightful and helpful. could you share your knowledge on which frequency range could be used for it?
