We overview the recent results of the research-and-development activities in Novosibirsk focused on improving conventional and creating novel elements in quasi-optical instrumentation for the millimeter-wave and terahertz bands of the electromagnetic spectrum. The elements include different components and devices based on single- and multi-layered metallized microstructures of subwavelength topology: frequency filters, non-profiled focusing devices, thin-film phase and polarization transformers, ultra thin metamaterial absorbers and absorber-based bolometric sensors. The aspects of electromagnetic modeling, fabrication, and characterization of the developed devices are described together with their practical applications. The seminar pursues the following goals:
- To inform the THz team of ANKA about some original high-performance solutions in mm-wave and THz instrumentation developed in Novosibirsk. The ANKA’s scientists are welcome to discuss the proposed ideas in context of their experimental demands. If necessary, some solutions (e.g. band-pass subTHz filters) can be readily designed and fabricated in Novosibirsk for further integration with THz metrological systems at ANKA.
- To discuss opportunities for NSU-KIT cooperation in technological implementation of some novel micro- and nano-structured optical devices. This topic mainly relates to the micro/nano-fabrication technologies which are well developed at KIT, such as LIGA. In particular, thin & planar focusing devices based on LIGA structures, as well as high-performance LIGA-filters will be considered.
