Table 1 Complex dielectric constants, i.e. Real and imaginary parts \(\:{\epsilon\:}^{{\prime\:}}\) and \(\:{\epsilon\:}^{{\prime\:}{\prime\:}}\), of PVA-TDBC samples having the same concentration and different thicknesses. \(\:{\epsilon\:}^{{\prime\:}}\) and \(\:{\epsilon\:}^{{\prime\:}{\prime\:}}\) of ag are close to those of Ref³⁵. Other works refer to data from the literature at \(\:\lambda\:=632.8\:nm\) for TDBC-PVA on glass substrates^26,36.
