Webspectroscopy (FTIR) was used to characterize the samples from ~33 to 3300 cm-1 (~ 1THz – 100 THz). The measurements from the three techniques are compared, and dielectric constant and loss data will be presented for commercial and experimental ceramic systems from 10 GHz to infrared frequencies. Key words: 1. Introduction WebFTIR spectroscopy in particular is of great interest due to the chemical information directly accessible and its high specificity in the fingerprint region (<1500 cm −1) [15,16]. It has …
