太赫辐射在很多领域,如传感、成像和光谱学都有应用的潜力。处于微波和可见光辐射之间的这种光谱区的波导仍是一种挑战.无论微波用的金属波导,还是可见光和近红外辐射用的介质波导,在远距离传输太赫波时都有高损耗,因为在太赫区,金属的电导率是有限,介质材料有高的吸收系数。
Terahertz radiation has potential applications in many fields such as sensing, imaging and spectroscopy. Waveguides in this spectral region between microwave and visible radiation are still a challenge. Both metal waveguides for microwaves and dielectric waveguides for visible and near-infrared radiation have high losses over terahertz waves over long distances Because in the terahertz area the conductivity of the metal is limited and the dielectric material has a high absorption coefficient.
