The 2.7 THz spatial filter consists of two diagonal feed horns connected by one wavelength of square waveguide (92 μm on a side). The mode filtering efficiency and far field beam pattern of the structure have been modeled in CST Microwave Studio. We have fabricated the filter in tellurium copper using a Kern MMP micromilling machine.
Micromilling is a type of micromachining process, which has wider scope in fabrication industries. Micromilling process involves mechanical interaction between the workpiece and sharp tool, resulting in the removal of material in the form of chips [1]. Components/parts for products in micro and nano domains are made with …
