Prof. Shiban Koul

Microstrip is the most used transmission line to design planar and flexible microwave integrated circuits due to its ease of fabrication, lightweight, and planar nature. However, the microstrip line has some disadvantages such as narrow bandwidth, high cross-talk, and higher transmission line losses. Spoof surface plasmon polariton (SSPP) based transmission lines can be used to overcome these disadvantages. The SSPP technology helps us to miniaturize the circuit because of its subwavelength resolution; unwanted filtering circuits can be reduced as SSPP works as low low-pass filter. In addition, cross-talk in SSPP is less as the fields are confined to the line.
The talk will discuss gaps between the conventional technology based on microstrip transmission lines and futuristic technology based on Spoof Surface Plasmon Polariton transmission lines. Starting from the basic SSPP Transmission line, the study of different components such as filters, antennas, and tunable components will be discussed. The talk will also focus on the study of SSPP technology for biomedical applications. Textile and Flexible antennas are gaining popularity these days because of their applications in defense and daily use gadgets. These important aspects are also studied in this talk using SSPP technology.
