IETE-SF organized a lecture on Smith Charts. It was an hour-long lecture, conducted on 17th of February, at 4.30 pm. The lecture was delivered by Dr. Amit Deshmukh, HOD of EXTC department, with students as well as teachers in attendance.
About the lecture
Dr. Amit Deshmukh started off the lecture by the introduction of Smith Charts. The Smith chart, invented by Phillip H. Smith, is a graphical aid designed for electrical and electronics engineers specializing in radio frequency (RF) engineering to assist in solving problems with transmission lines and matching circuits. The purpose of its development was to simplify calculation of reflection coefficient in Antenna and microwave systems, as calculation using formula becomes too complex and time consuming.
After touching upon a few prerequisites required to understand Smith Charts, he talked about the calibration of a Smith Chart. He explained that a smith chart is nothing but mapping of impedance domain to Reflection domain. He proceeded to explain how to actually represent and read data from a Smith Chart, demonstrating how simple it makes an otherwise complicated task. After explaining a few examples, he concluded the lecture by drawing attention towards various applications of Smith Charts and its importance in the field of Telecommunication.
Smith Chart is a powerful tool for microwave analysis and antenna design. Because of its simplicity, it is also one of the most widely used tools, which makes it a very important topic. Since it is not included in the curriculum, IETE-SF took the initiative to educate students in this respect. The event was well organized and IETE-SF’s team received amazing feedback for this initiative and their hard work.
