Why does the transmission spectra shows an increase near the optical absorption edge?

Measuring a transmission spectrum of thin film (eg: single phase oxide) using UV-Vis spectroscopy, the transmission value gradually increases as we decrease the wavelength and reaches a peak until...

Why does the dielectric constant decreases under high electric fields?

Why does the permittivity decreases when a voltage is applied on the sample. On applying voltage, the dipolar polarization will increase and therefore the permittivity should increase. Instead,...

Why do metal-oxide composites show higher permittivity/refractive index as compared to pure oxide?

Since metals (eg: Au) show negative permittivity, the metal oxide composite should should show lower permittivity compared to the pure oxide phase. But standard methods such as Effective Medium...
