Mr. Cheng Zhao


A Waveguide filter is one of the most important components in microwave and millimetre systems.

Before the computer age, the traditional method to design a waveguide filter is equivalent circuit method. However, the precision is not preferable, because this method ignores the influence caused by high order modes which are excited by discontinuities in waveguides.

With the development of computer technology, many numerical methods based on full wave analysis, such as Finite Difference Method (FDM), Finite Element Method (FEM), and Mode Matching Method (MMM) and so on, are applied to design waveguide filters. Compared to other methods, Mode Matching Method has the advantages of fast speed and high accuracy. Thus, it has great significance to shorten the development cycle, lower production costs and improve efficiency.

This seminar will introduce the theory of Mode Matching Method, the procedure of designing a W-band Iris Band Pass Filter and analyse some influence caused by processing precision.




Cheng Zhao obtained his bachelor’s degree from the School of Information Science & Engineering, Southeast University, China and his master’s degree from the School of Electrical & Electronic Engineering, the University of Adelaide in 2011. He was awarded the Australian Postgraduate Award (APA) pursue his PhD research in the School of Electrical & Electronic Engineering, the University of Adelaide. His research interest includes Mode Matching Method, the waveguide to microstrip transition, etc.
