Bio

Dr. Aiswarya S. is an Assistant Professor at the Amrita Center for Wireless Networks and Applications, Amrita Vishwa Vidyapeetham, Amritapuri. She holds a Ph.D. in RF and Microwave Engineering with a thesis entitled “Design and Development of Chipless Radio-Frequency Sensors Based on Planar Microstrip Resonators in Frequency Domain”. She received her M.Tech in Wireless Networks and Applications and B.Tech in Electronics and Communication Engineering. Her research interests include microwave planar devices, antennas, wireless communications and networking, IoT, RF design development and testing.

She has expertise in designing and fabricating different types of antennas, filters, and RFIDs using software like ANSYS Electronics Suite, ANSYS HFSS, DESIGNER, ADS, etc. She designed and fabricated several band-pass and band-stop filters for communication and passive spiral RFID tags for detection. She performed measurements for acquiring various dielectric and scattering parameters of materials using a Vector Signal Analyser. She gained hands-on experience calibrating instruments like Vector Network Analyser, Field-Fox Handheld RF and other Microwave Analysers. Her knowledge in configuring Ubiquity RF modules, Ubiquity CPE, and Linksys router had helped very much in its installation as a part of system integration in a funded project. As a team member, she was well involved in projects for miniaturising HF antennas for Naval Applications and studying radiation effects on the living things and their heating effects.

She had actively participated as a lead member in the development of ‘AMRITATARANG – Advanced RF & Microwave Research Lab’ in Amrita Center for Wireless Networks & Applications, Amrita Vishwa Vidyapeetham, launched during Amritavarsham 70. She had also actively participated as a team member in the project ‘Jivamritam’, a Community-based Safe drinking water solution, a program to provide clean drinking water to 5,000 villages.

Dr. Aiswarya S has attended several International conferences/workshops and presented technical papers. She has more than 25 international publications to her credit, including five high-quality journal publications.

Dr. Aiswarya worked as a Research Associate at the Center for Wireless Networks & Applications from 2016 to 2023. The research projects worked during the tenure are as follows:

  1. Worked on a project titled ’MICRONet – Mobile Infrastructure for Coastal Region Offshore Communications & Networks’, funded by the Information Technology Research Agency (ITRA), Ministry of Electronics and Information Technology (MeitY), Government of India. The project evaluates the technological options to provide an effective and reliable way for the fishermen to communicate among themselves and with the shore during emergencies and other times. [Time span: 08/2016 – 08-2019]
  2. She worked on a project titled ’4WARD –Fast forward to SDG6: Acceptable and Affordable Water in Secondary Indian Cities’, funded by the Department of Science and Technology, Government of India. The project objectives are to develop and demonstrate a programmatic approach towards real-life problem-solving in the Urban Water Systems, adopt a participative process of co-design integrated with the Digital Social Platform (DSP) for balancing engineering solutions with public acceptance and institutional design/arrangements and to present a replicable model by demonstrating improved water supply and sanitation even under the extreme surface and groundwater quality challenges at selected four pilot case studies (living labs) embedded in DSP. [Time span: 03/2021 – Present]
  3. She has guided various research projects for postgraduate and graduate students in Antennas, Microwave Engineering, Wireless Communications and Networking Experience in handling the role of department publication coordinator.
