Periodic structure towards the terahertz region manufactured using high resolution 3D printing

摘要: Periodic structures used for high power millimetre and sub-millimetre sources that implement relativistic beam — wave interactions have historically involved the implantation of a dielectric layer around inner wall interaction region or periodic corrugated structure serves to reduce velocity an internal electromagnetic wave. Moving towards THz regime, physical dimensions required manufacture such cavity become prohibitively difficult. Ongoing attempts develop manufacturing processes provide higher resolution resulted in number viable techniques. Additive Manufacturing 3D printing offers possibility producing components on this scale quickly efficiently. Here 0.1, 0.4 1 are realised using (16 micron) technology.
