Workshop Program

This tutorial session provides fundamentals and applications of microwave filters for students and beginners. The session aims at mastering the basics of practical filter design methods, and finally des igning microwave filters by themselves.
In the first half of the session, the microwave filter fundamentals, including circuit theory and network synthesis, are explained. In the second half, furthermore, the basic theory is followed by design examples of microwave filters from the viewpoints of both practical filter realizations and applications.

This tutorial session explains the algorithm used in electromagnetic simulators and discusses effective way of using the simulators.
Electromagnetic simulators are used for designing high frequency circuits, and are indispensable not only in industry but also in universities as the research and educational tool. The accuracy of an analysis result and the speed of analysis are of great concern. Many commercial simulators spread and the environment where calculation can be performed easily is ready today. However, the simulators are becoming "black-boxes" at the same time, and it is becoming difficult to check if they work properly, or to interpret the result correctly. It is very useful for the early detection of a mistake to know the algorithm of a simulation as the words "the more haste, the less speed."
