Ensuring the Reliability and EMC by Modal Reservation: A Brief History and Recent Advances

Abstract

With the growth of the radioelectronic complexity and the demand for cutting edge devices, the need to protect them and increase their reliability is also rising. There are many methods to provide this. Modal reservation is one of the most effective, reliable, and least complicated methods used nowadays. Using this method in tracing and mounting of printed circuit boards can guarantee both electromagnetic compatibility (by using modal filtering) and reliability (by using the cold redundancy) of the final electronic device. Modal reservation was proposed in 2015, and since then, massive research has been conducted on its investigations and development including 18 patents for inventions. Most of these studies have been devoted to modal reservation in terms of conducted emissions. However, up to now, a general and comprehensive review of modal reservation and investigations of its application with respect to radiated emissions has not been performed. Therefore, this paper aimed at presenting such a review on the history and recent research on modal reservation, concentrating on the studies related to radiated emissions. In addition, this paper analyzes current studies on the efficiency of using modal reservation under climatic impact.
