Abstract-Terahertz rare-earth orthoferrite metamaterials by 3-D direct writing technology
Terahertz (THz) radiation excites electronic and optical modes of many materials, and controlling interaction of these materials with THz pulses provides a fascinating avenue to achieve unprecedented functionalities in return. Here, woodpile-structured rare-earth orthoferrite metamaterials built with 3-D direct ink writing technology are proposed and experimentally demonstrated. Polarization-independent THz refraction and switching of resonances by varying the number of layers in the structure, as well as the structural parameters and specimen support angle are achieved. Such all-rare-earth-orthoferrite dielectric metamaterials are easy to fabricate and can be very promising in developing efficient and low cost THz functional metadevices.
