Abstract :
In this study a terahertz wire-grid polarizer was manufactured using ruling based ultra precision diamond machining process and replicated to TPX (Polymethylpentene) using hot embossing. Imprinted structures were evaporated with aluminum in a slanted angle so that an aluminum grid was formed. Polarizers were tested with THz-spectrometer.
