Excitonic light emitting devices based on two dimensional transition metal dichalcogenides

October 25, 2019 @ 3:00 pm - 4:00 pm
ESB – 244

Date/Time: 25th October 2019, 1500 hrs Venue: ESB 244 (Electrical Engineering Seminar Hall) Speaker: Ankit Arora (EE16D025) Guides: Prof. Ananth Krishnan (EE) and Prof. M. S. Ramachandra Rao (PH)   Abstract   Two-dimensional transition metal dichalcogenides (TMDs), such as MoS2 and WSe2 form a class of atomically thin, direct band semiconductors, with the bandgaps in the visible or near Infrared (NIR). These materials exhibit strong light-matter interaction with stable excitons even at room temperature and are potential candidates for various…

Motion Deblurring For Rolling Shutter and Light Field Cameras

February 20, 2020 @ 2:00 pm - 3:00 pm

Date: 20.02.2020 (Thursday)   Time: 2 p.m.   Venue: ESB 244   Speaker: Mahesh Mohan M R (EE14D023)   Guide: Dr A. N. Rajagopalan   DC Members: Dr Devendra Jalihal  (Chairperson) Dr Aravind R  (EE) Dr Arun Pachaikannu (EE) Dr Chandra Sekhar (CSE)   Abstract Most present-day imaging devices are equipped with CMOS sensors. Motion blur is a common artifact in hand-held cameras. Because CMOS sensors mostly employ a rolling shutter (RS), the motion deblurring problem takes on a new…

Asynchronous Communication

February 20, 2020 @ 3:30 pm - 4:30 pm
ESB 244

Name of the speaker : Ms. Vidyalakshmi Dani (EE16D001) Guide : Dr. Venkatesh R PhD Seminar I The emerging wireless applications such as the Internet of Things (IoT), machine type communication and cyber-physical systems are important use cases of 5G services. Compared with traditional networks, a distinguishing feature of communication in these applications is the inherent asynchronism in communication, i.e., the nodes transmit information sporadically. For example, a sensor node may send a few hundred bits of information every few…

Wire Antennas on Finite Ground Planes

March 19, 2020 @ 3:00 pm - 4:00 pm
ESB – 244

Title:  Wire Antennas on Finite Ground Planes Date: 19.03.2020 Time: 3.00 p m Venue: ESB 244 Speaker: R. Rajavaradhan (EE12D202) Guide: Dr. Harishankar R ABSTRACT Antennas can be regarded as structures facilitating the accelerating currents to radiate and vice-versa. The characteristics of antennas mounted on other structures vary drastically from that of the standalone ones because of the induced currents on the structure. Small satellites are a good example of such structures. The antenna characteristics are often simulated using commercial…
