The aim of the joint DFG-RFBR research proposal MACRAME is to invent, investigate, and establish new design guidelines for RF circuits and systems that are lacking in conventional approaches. The project isdevoted to pioneering conceptual, theoretical, and experimental research on one-dimensional metamaterials employing active positive (conventional) as well as negative (non-Foster) capacitive and inductive constituents.Based on such an approach, novel miniature multi-band or ultra-wideband filters and oscillators composed of distributed amplifying and selective elements shall be devised and implemented. Due to their active nature, these devices can in addition be designed electronically tuneable orreconfigurable. Achieving these properties fills a gap in present circuit technology. Applications are manifold and concern future wireless system applications in mobile and satellite communications, biomedical diagnostics, sensing, automation, and security issues.MACRAME complies with the research cooperation between the Governments of the Federal Republic of Germany and the Russian Federation. With MACRAME, the two universities in Ilmenau and St. Petersburg wish to intensify their fruitful co-operation on the basis of a coherently conducted bilaterally funded research, taylored to the complementary areas of expertise and partly covered by the Russian-German Engineering Faculty at ETU. We expect significant synergy effects through exchange of scientists, dissemination of knowledge and ideas, leading to enhanced quality publications and international reputation.
