Dual-parameter bianisotropy

Definition

Dual-parameter bianisotropy refers to the property of certain materials where both electric and magnetic responses depend on both the electric field and magnetic field applied to them. This characteristic leads to a more complex interaction between electromagnetic waves and the material, influencing how light behaves when it encounters the material. It allows for advanced functionalities in metamaterials and photonic crystals, which can be utilized in applications like negative refractive index materials and electromagnetic wave manipulation.
