Prof. Saha of IIST, Thiruvananthapuram

The rapid growth of IoT devices, wireless sensors, autonomous systems, aerospace platforms and connected electronics is creating a growing need for reliable and convenient power delivery. Dependence on batteries and wired charging brings challenges such as limited battery life, frequent replacement, maintenance, difficult access to remote devices, and electronic waste. For large-scale and distributed wireless systems, providing power efficiently and reliably can become as challenging as providing connectivity.

Emerging Opportunity: Microwave wireless power transfer and RF energy harvesting offer new possibilities for delivering energy without physical connections and powering devices where conventional charging methods are difficult or impractical. The integration of RF energy generation, transmission, antennas, rectennas, power management and efficient microwave systems can open new pathways towards more sustainable and autonomous electronic systems.

Samabasiva Rao of RCI, DRDO

Modern RF, radar and defence systems increasingly require precise control of electromagnetic waves, while also demanding compact, low-profile, efficient and highly integrated solutions. Conventional conducting surfaces may not provide the flexibility required for advanced wave manipulation. PMC and RIS engineered surfaces provide a powerful framework for controlling electromagnetic boundary conditions and tailoring the interaction of electromagnetic waves with surfaces. Metamaterial-based implementations open opportunities for realizing engineered surfaces with properties that are difficult to achieve using conventional materials.

Reconfigurable Intelligent Surfaces (RIS) based on space-time modulated metasurfaces have emerged as a promising means to enhance next-generation wireless networks, by allowing control over the radio propagation environment. This talk will first discuss the design and fabrication of an indigenously built one-bit coded reconfigurable metasurface based RIS. Then, opportunistic communication will be highlighted as a means of eliminating the overhead involved in RIS optimization. Then, an IDM (infinitesimal dipole modelling) based approach to compute the scattered field and power density from RIS (reconfigurable intelligent surfaces), for both far-field (FF) and near-field (NF) illumination scenarios will be highlighted. Finally, the use of such modulated metasurfaces for designing multi-beam and beam-steering antennas will be discussed.

In the modern communication era, antenna arrays play a vital role, demanding more constrained antenna arrays with high gain, ultra-low sidelobes, etc. The introduction of the fourth dimension, time in antenna arrays, reduces the effort needed for synthesis and offers flexibility in designing high-performance antenna arrays. The fourth-dimensional antenna with time as the fourth dimension is also known as Time-Modulated Antenna Array (TMAA). The modulation of the antenna array by periodic time sequence generates harmonic radiation patterns. This talk provides a review on TMAA from its evolution to the current progress including the implementation and its applications like secure communication, tracking of elements, and simultaneous scanning in azimuthal and elevation planes, radiating sum-difference patterns, multi-tone radiation, Wireless Power Transfer.
