We have developed a new 3D printing technology which can make three-dimensional metallic structures with sufficient resolution for making THz metamaterial. As a demonstration to show the advantage of our technology, we made a “thick” THz metamaterial with 1-mm thickness, which is larger than the typical THz wavelength. This device works as high-pass filter with a sharp cut-off frequency because of the thick characteristic.
