In recent years, as the spectrum resources are getting scarce, microwave filter designs become complicated to achieve high performance responses. Therefore, electromagnetic (EM) simulators are now indispensable for such filter designs, but the high performance filters cannot be realized only by EM simulations. The essence of microwave filter designs is the circuit theory and the network synthesis method, and thus the establishment of a new design theory is required for the creation of new microwave filters.
This workshop focuses on the latest design theory and circuital approaches beyond the classical filter theory, and also introduces the applications of the design theory to ultra-narrow bandpass filters, unbalanced-balanced filters, and multi-mode filters.
