Abstract

THz time-domain spectroscopy (THz-TDS) is by now getting an established technique for the precise determination of the dielectric function of various materials in the terahertz spectral range of the electromagnetic spectrum. Typically, THz-TDS is carried out using planar samples. Examples include transmission spectroscopy of pressed pellets for the investigation of powder materials and wafer-like samples for spectroscopy of bulk and nanostructured semiconductor materials. Reflection-type spectroscopy is applied using plane interfaces for the study of liquids [1,2,3]. However, quantitative spectroscopy on samples with irregular shapes is very challenging due to the complicated interplay between spectroscopic signatures of the material and diffraction effects due to irregular sample geometry.
