Consider a uniform plane wave with amplitude $\left({\mathit{E}}_0\right)$ of $10\frac{\mathit{V}}{\mathit{m}}$ and $1.1\mathit{G}\mathit{H}\mathit{z}$ frequency travelling in air, and incident normally on a dielectric medium with complex relative permittivity $\left({\mathit{E}}_{\mathit{r}}\right)$ and permeability $\left({\mathit{\mu }}_{\mathit{r}}\right)$ as shown in the figure

The magnitude of the transmitted electric field component in $\left(\mathit{V}∕\mathit{m}\right)$  after it has travelled a distance of 10 cm inside the dielectric region is______
