a Measurement of \({{{\boldsymbol{V}}}}_{{{\boldsymbol{PD}}},{{{\boldsymbol{B}}}}_{{{\boldsymbol{mod}}}}}^{{{\boldsymbol{Cu}}}}\) (blue solid line) and \({{{\boldsymbol{V}}}}_{{{\boldsymbol{PD}}},{{{\boldsymbol{L}}}}_{{{\boldsymbol{mod}}}}}^{{{\boldsymbol{Cu}}}}\) (red solid line) vs. \({{{\boldsymbol{B}}}}_{{{\boldsymbol{AC}}}}\) and \({{{\boldsymbol{B}}}}_{{{\boldsymbol{DC}}}}\), respectively. b Measurement of \({\sqrt{\widetilde{{{\boldsymbol{V}}}}}}_{{{\boldsymbol{PD}}},{{{\boldsymbol{B}}}}_{{{\boldsymbol{mod}}}}}^{{{\boldsymbol{Cu}}}}\) vs. \({{{\boldsymbol{B}}}}_{{{\boldsymbol{AC}}}}\). Dashed blue line represents a linear fit for data in the range of \({{{\boldsymbol{B}}}}_{{{\boldsymbol{AC}}}} > {{\bf{200}}}{{\boldsymbol{mT}}}\). c Schematic illustration of the modeled interaction. The transmitted field, \({{{\boldsymbol{E}}}}_{{{\boldsymbol{y}}}}^{{{\boldsymbol{t}}}}\left({{\boldsymbol{z}}}\right)\), propagates in the metal and generates the reflected field \({{{\boldsymbol{E}}}}_{{{\boldsymbol{x}}}}^{{{\boldsymbol{r}}}}\).
