“…A new additive technology based on photopolymer 3D printing, which is currently being actively applied at the IAP RAS, was used to produce a model of a modified Bragg reflector [29,30]. Within the framework of this technology, plastic is polymerized in layers via UV radiation passing through a liquid crystal LCD screen, while the high resolution of LCD matrices allows us to achieve a minimum size of roughness in all coordinates of no more than 20 microns.…”

“…Thus, new technologies ensuring a quick and inexpensive manufacturing of experimental samples of sets of these sub-THz mirrors are required. The IAP RAS actively implements a novel additive technology based on photopolymer 3D printing together with the chemical metallization of photopolymer-based structures (CMPS) [29,30]. The use of this technology allows us to create components of complex forms with small-scale elements.…”

A novel concept of a frequency-tuned sub-terahertz gyrotron based on a combination of an irregular low-frequency resonator and an external reflector has been proposed recently. A simulation was carried out for a fundamental-cyclotron-harmonic gyrotron that demonstrates the possibility of achieving high (10–30%) efficiencies in a wide (~10%) frequency range. A possible solution to the problem of narrow-band frequency-tunable external reflectors in the form of so-called modified planar Bragg structures is discussed. The manufacturing of such structures on the basis of a novel additive technology based on photopolymer 3D printing, as well as the results of “cold” experiments of the manufactured samples, are described in the paper.

In this paper, we studied the operability of various components of vacuum electronic devices manufactured using the novel chemical metallization of photopolymer 3D-printed structures technology (CMPS), which is being applied at the Institute of Applied Physics, Russian Academy of Sciences (IAP RAS), for operation from microwave to sub-terahertz ranges. The key feature of this production method is the 3D printing (SLA/DLP, MJM technologies) of products and their further metallization. The paper presents the main stages of the process of chemical copper plating of polymer bases in various electrodynamic systems with complex shapes. A significant difference in the geometry and operating conditions of the created elements forms certain approaches to their production, as described in this work. Experimental studies of the implemented microwave components were carried out up to 700 GHz in the “cold” measurements; some electrodynamic structures were examined under conditions of sub-gigawatt peak power; and complex-shaped electrodes with cooling channels were tested under a continuous high thermal load. The conducted research has demonstrated the high potential of the developed methods of additive manufacturing of microwave device components and the prospects for their successful application in the described areas.
