Filter design principles will be reviewed and the new MatLab-based filter design software – MWFilterDesigner – will be discussed [1]. The beauty of the software lies in that it automates all design steps starting from lumped element LC filters using classical methods, then obtains corresponding TL and ML filters via systematic transformations. All the schematics of the LC, TL, and ML filters are drawn automatically. Note that, BPFs require SC stubs and this is also implemented in the MWFilterDesigner. Moreover, the ML structure is exported automatically in a GDSII format which makes full-wave electromagnetic simulations with variety of commercial packages possible. One only needs to run a commercial package, open the input file generated by the MWFilterDesigner and push the start button. The designed filter is then analyzed and optimized by means of a full-capable, 3D Finite-Difference Time-Domain (FDTD) method based simulator MSTRIP [2]. Characteristic examples will also be presented. References [1] A. Uslu, L.

Biography: Levent Sevgi received the Ph.D. degree from Istanbul Technical University and Polytechnic Institute of New York, in 1990. Prof. Leo Felsen was his advisor.
He was with Istanbul Technical University (1991–1998), TUBITAK-MRC, Information Technologies Research Institute (1999–2000), Weber Research Institute/Polytechnic University in New York (1988–1990), Scientific Research Group of Raytheon Systems, Canada (1998 – 1999), Center for Defense Studies, ITUV-SAM (1993 –1998, 2000–2002). He has been with Doğuş University – Istanbul since 2001 and with University of Massachusetts Lowell (UML) since September 2012.
He has been involved with complex electromagnetic problems and systems for more than 20 years. His research study has focused on propagation in complex environments, antenna and microwave circuit design, analytical and numerical methods in electromagnetics, EMC/EMI modeling and measurement, radar and integrated surveillance systems, surface wave HF radars, FDTD, TLM, FEM, SSPE, and MoM techniques and their applications, RCS modeling, bio-electromagnetics. He is also interested in novel approaches in engineering education, teaching electromagnetics via virtual tools. He also teaches popular science lectures such as Science, Technology and Society.
Prof. Sevgi is a Fellow of the IEEE, the writer/editor of the “Testing ourselves” Column in the IEEE Antennas and Propagation Magazine and a member of the IEEE Antennas and Propagation Society Education Committee.
