La concentration dependence (5−20%) of the TC-EMS performance of \({\mathrm{BLSO}}_{{\mathrm{MgAl}}_{2}{\mathrm{O}}_{4}}^{\mathrm{MgO}}\). a The sheet resistance of \({\mathrm{BLSO}}_{{\mathrm{MgAl}}_{2}{\mathrm{O}}_{4}}^{\mathrm{MgO}}\) decreases with a decrease in the La concentration. b The conductivity of \({\mathrm{BLSO}}_{{\mathrm{MgAl}}_{2}{\mathrm{O}}_{4}}^{\mathrm{MgO}}\) and \({\mathrm{BLSO}}_{{\mathrm{SrTiO}}_{3}}\) is maximized in Ba0.95La0.05SnO3 whereas that of \({\mathrm{BLSO}}_{{\mathrm{MgAl}}_{2}{\mathrm{O}}_{4}}\) is invariant. c The infrared transmittance of \({\mathrm{BLSO}}_{{\mathrm{MgAl}}_{2}{\mathrm{O}}_{4}}^{\mathrm{MgO}}\) decreases with a decrease in La concentration, but the ultraviolet–visible transmittance does not change; this is shown more clearly in (d). e The SE of \({\mathrm{BLSO}}_{{\mathrm{MgAl}}_{2}{\mathrm{O}}_{4}}^{\mathrm{MgO}}\) increases with a decrease in La concentration. f The SEA and SER at 10 GHz also increase
