| Title | Role of Electromagnetic Simulations in Commercial Product Design |
| Details | Wireless devices such as mobile phones, tablets etc. have become part of our daily life. Emerging Technologies, 5G/6G, Autonomous Driving, automated delivery systems, smart homes, smart cities will revolutionize the way we live, work, and communicate soon. A key component in all these technologies is an antenna or multiple antennas that are used for transmitting and receiving signals. As a result, many products we use today and will be using soon, will need to incorporate antennas that are efficient and can fit within the space available in the device. Advances in simulation technology using computational electromagnetic tools have made possible antenna design and integration of antennas into various devices. In this talk, we will review advances in EM computational methods in the context of product design process in various industries.

| Title | Flattening the Risley Prism Using Metasurfaces For Antenna Beam Steering |
| Details | An old far-field optical concept called Risley Prism has inspired the speaker to invent a ground-breaking antenna beam steering technology for radio-frequency, microwave, millimeter-wave and Terahertz systems. Published in the seminal paper in IEEE Transactions on AP in 2017, this method has become popular across the globe among academia, industry and government sectors. It is now known by several names including Near-Field Phase Transformation, Near-Field Meta-Steering and Near-Field Risley Prism. Among the industry adopters of this method are Thales Research and Technology in France and WaveUp in Italy. This distinguished lecture will outline the method and describe several implementations of it by his team and other researchers in academia as well as in industry.

| Title | ITRC (In-Situ Testing of Radio Communication) on Wearable IoT Devices Embedding Metamaterial RF Sensors |
| Details | IoT networking, Wearable sensors are exemplified by the heart-beat checker, body-temperature measurer, sweat chemical reader and the like. They transform physical or chemical phenomena to electric voltages and currents which are saved as data, which are forwarded to their communication block to be delivered through the air to nodes for picking up the signals. This is being done in smart watches or earphone gadgets. The makers and service providers desire the devices and quality of the IoT to be compact and quite high, respectively, which necessitates novel approaches to overcome the shortcomings of the conventional methods stemming from the use of half-wavelength based antennas of ceramic, FR4 etching and LDS manufacturing processes. Instead of folding the dipole or patch antennas to be fit into the small foot-print as shown in a smart watch or earphone, the RF sensors for radio communication are designed on the basis of metamaterials. The zero-index with the effective epsilon and mu is adopted to enable an extremely small structure to resonate for electromagnetic radiation at the target frequency very low with reference to that of the same size. Though the RF sensors are electrically small, the properties of their radiated waves in terms of antenna gain as well as return loss are good, which leads to high sensitivity in giving and receiving the signals in the IoT network of interest. The design method is validated by prototyping and the fabricated protypes go through In-Situ Testing of Radio Communication (ITRC). They will unveil high-level and diverse applicability to the IoT scenes.

| Title | Human-Centric Radio Wave Control |
| Details | Wireless technologies have enriched modern life through smartphones and wearable devices. As wireless systems operate ever closer to the human body, radio waves are expanding beyond communication to human sensing and wireless power transfer, creating new requirements for safety, reproducibility, and intuitive interaction.
This talk presents three human-centric radio wave control technologies. First, human-aware beamforming reduces human exposure to RF fields while maintaining desired wireless functions. Second, the Life-Emulating Intelligent Electromagnetic Phantom (LiePH) reproduces human electromagnetic responses for efficient and repeatable over-the-air testing of wireless human-sensing systems. Third, motion-driven beamforming uses human motion and its micro-Doppler signatures as an intuitive interface for controlling radio transmission. These studies provide new directions for future wireless systems integrating communication, sensing, and wireless power transfer.
