Time domain spectroscopy is used to determine the THz electromagnetic response of amorphous transition metal dichalcogenides WSe₂ and MoSe₂ in thin-film form. The dielectric function is obtained using a rigorous transmission model to account for the large etalon effect. The Drude⁻Smith model is applied to retrieve the dielectric function, and from there, the sample conductivity.
