Hello,
I am looking for material which has electric field dependent anisotropic electrical conductivity.
Say for instance, its conductivity in x-direction (sigma_xx) changes with the applied E-field in y-direction (Ey). Is there any real material like this or even metamaterial. Please kindly, let me know your wise suggestion. Thanks !!
Electric field dependent properties implies a non-linear optical material. You could try a non-centrosymmetric material such as lithium niobate, which has dielectric constants that are electric field dependent as well as having some crystal orientation dependence. You may want to refer to Yariv's book on Quantum Electronics (chapter on second harmonic generation). I'm not too sure about conductivity, but starting with dielectric permittivity might be helpful.
Let me see what can I find useful there ! Thanks a lot Indrasen for your response and the book !!!
