Abstract :
Temperature dependencies of both reflection and transmission coefficients have been measured in frequency range 37-50 GHz. It has been shown that there exist characteristic microwave frequencies associated with only ferroelectric pre-transition temperature region at 37 GHz, with only paraelectric pre-transition temperature region at 40 GHz, and with the whole pre-transition temperature region at 38 GHz and 50 GHz. These frequency features has been attributed to 3-component NMR spectra in TGS.
