comment How do we predict electrical properties of a material using scattering data and vice-versa?
Suggestion to the question (v2): Instead of the verb predict use e.g. measure or calculate.

Hi user2856118. Welcome to Phys.SE. (For the record: CuriousOne's and my actions were independent.) If you haven't already done so, please take a minute to read the definition of when to use the homework tag, and the Phys.SE policy for homework-like problems.

comment Why are these two definitions for symmetries in the Lagrangian equivalent?
@Void: In my convention $d_{\mu}\equiv\frac{d}{dx^{\mu}}$ and $\partial_{\mu}\equiv\frac{\partial}{\partial x^{\mu}}$ denote the total and the explicit spacetime derivative, respectively. See e.g. my answer here.
