Summary: 
In this paper, an experimental result of complex refractive index of soda-lime glass at 30-GHz obtained by transmission method is presented at first. Secondly, a simple empirical formula of complex refractive index of soda-lime glass over frequency range from 0.1-GHz to 1000-GHz is derived using the present experimental result together with data previously reported in literatures by various researchers.
