Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
The principles of constructing high-order microstrip filters based on single- and dualresonator highly selective sections are being developed. It is shown that a significant increase
of microstrip structure selectivity with a minimum number of resonators can be achieved by
using the method of "reverting" of the transmission zeros, the effect of combining the main and
parasitic passbands, as well as the galvanic connection of the sections instead of their cascade
connection.
