摘　　要：The performance of a terahertz （THz） Brewster polarizing beam splitter on polymer substrate is studied theoretically and experimentally. Simulations by using finite-element method demonstrate that both trans- nqittance/rei%ctanee and their extinction ratios are better than its 45 °counterpart in a broad frequency range. Especially, the reflection extinction ratio improves significantly. The results are also verified exper- imentally with THz time domain spectroscopy （TDS） and backward wave oscillator （BWO） measurement system.The performance of a terahertz （THz） Brewster polarizing beam splitter on polymer substrate is studied theoretically and experimentally.
