Colloquium on Metamaterials and their Applications in Metrology by Prof. Achanta Venugopal

The Department of Physics, School of Natural Sciences, is delighted to extend an invitation to you for a special colloquium featuring Prof. Achanta Venugopal, the distinguished Director of CSIR National Physical Laboratory. This enlightening session, titled "Metamaterials and their applications in metrology," promises a deep dive into the fascinating realm of Metrology – the science of high precision measurements that underpins a nation's quality infrastructure and international trade facilitation. Prof. Venugopal will shed light on the innovative use of metamaterials, specially designed materials with sub-wavelength features, and their potential in achieving heightened accuracy and efficiency in measurement systems. Join us on 17th April 2024, from 12 PM to 1 PM (IST) at venue C-021, to explore the groundbreaking advancements in this field and learn about the pivotal role CSIR-NPL plays as India's leading Metrology institute.

Abstract:

Metrology is the science of high precision measurements. The national primary standards are set up and maintained at the National Metrology Institute in each country. These primary standards form the basis for the quality infrastructure within the country and also helps in international trade. As Metrology institute of India, CSIR-National Physical Laboratory has the primary standards that are globally acceptable. With the new definitions of the international system (SI) of units, new facilities are being developed to lower the uncertainty in measuring SI and derived units. Miniaturization for portability and energy efficiency requires novel ideas. Metamaterials are designed materials for specific applications and have sub-wavelength features. In this talk, after a brief introduction to Metrology and the activities at NPL, the concept of several metamaterials will be introduced along with their applications ranging from single photon emitter to single molecule detection.

Speaker Bio:

Prof. Achanta Venugopal did his M.Sc. in Physics from Central University Hyderabad. He obtained PhD in Physics from TIFR in 2000 for his work on Exciton dynamics in low dimensional semiconductors. In 2006 he was awarded PhD in Electronics Engineering from Tokyo University for work on design and demonstration of an ultrafast all-optical switch. This work was done as a NEDO Fellow at the headquarters of Japanese National Femtosecond Technology project, FESTA Labs between 2000 and 2003. From 2003 to 2004 he worked as a JST Fellow in the Quantum Information Technology group, Basic Research Labs, NEC, Japan. He joined TIFR as faculty in 2004 where he has been a Professor(H) since 2018. His research interest is in classical and quantum information processing with dipolar emitters like quantum dots embedded in photonic and nanophotonic structures. He joined CSIR-NPL as Director in June 2021.
