Lin Weigan, male, Han nationality, is a native of Taishan, Guangdong Province. He graduated from Tsinghua University and obtained a doctorate degree from California State University in the USA in 1951.
Lin has been a professor at Electronic Science and Technology University. In his work titled "Theory on One-Cavity-Multi-Mode Microwave Filter", he took the lead in discovering that there were five same resonance frequency degenerate modes available for use in one column resonance cavity, given due recognition from the counterpart, and this theory is still cited widely today. Among over one hundred scientific dissertations published, Lin's most important concerned his research on the application of conformal transformation. In the second volume of "UK Markni Series", his data and formula on special section of outer circle and inner square has been extensively cited. His formula and data about reactance resistance was considered the most exact, contributing to the study in colleges and universities. In 1989, Lin won the national level award First Excellent Teaching Results. In 1999, he was awarded the He Liang-He Li Science and Technology Advancement Award.
Lin Weigan was elected an academician of the Chinese Academy of Sciences in 1980.
