Future cities will require communication networks that go far beyond data connectivity, evolving into intelligent platforms capable of sensing, understanding, and interacting with the physical world in real time.

This talk will explore the emerging convergence of integrated sensing, communication and computing as a foundational paradigm for enabling cognitive cities, where wireless infrastructure acts not only as a communication medium but also as a distributed perceptive and decision-making system.

A central focus of the talk will be on Reconfigurable Intelligent Surfaces (RIS), an emerging technology that enables programmable control of electromagnetic wave propagation through software-defined metasurfaces.

RIS offers a transformative approach for next-generation 6G systems by dynamically manipulating the amplitude, phase, and polarization of radio waves to improve communication, sensing, and localisation performance.

In communication networks, RIS enhances spectral and energy efficiency, extends coverage in Non-Line-of-Sight environments, and enables intelligent beamforming with very low hardware complexity and power consumption.

Beyond communications, the talk will highlight how RIS-enabled integrated sensing and communication (ISAC) systems can support high-accuracy environmental perception and human-centric sensing, including real-time monitoring of heartbeat and respiration in challenging indoor and obstructed environments.

The integration of sensing and edge computing capabilities further enables context-aware and adaptive services for healthcare, mobility, smart homes, and urban infrastructure.

Collectively, these technologies are paving the way toward sustainable, resilient, and intelligent wireless ecosystems capable of supporting the vision of cognitive cities.

Wideband direction finding requires antenna arrays and beamforming systems that maintain consistent performance over a broad frequency range.

This talk introduces an integrated approach that addresses this challenge from the perspectives of antenna design, beamforming algorithms, and hardware implementation.

First, an ultrawideband connected array antenna incorporating artificial dielectric layers is presented. The artificial dielectric structure enables broadband operation while supporting a compact and practical array configuration.

A frequency-invariant beamforming method is then introduced to generate stable sum and difference patterns across frequency.

By combining these patterns with a monopulse-based direction-finding approach, the proposed method provides rapid angle estimation without conventional beam scanning while maintaining consistent angular coverage over the operating band.

Finally, the frequency-dependent weights required by the algorithm are implemented using a passive analog beamforming network composed of microwave filtering, combining, and hybrid-coupler structures.

Simulation and measurement results are presented to demonstrate the feasibility of realizing the proposed beamforming characteristics in practical hardware.

The talk highlights how antenna, algorithm, and circuit design can be jointly considered to develop compact and broadband direction-finding systems.

In this talk, I will discuss the challenges and opportunities associated with radiating systems in the near field for communications and sensing.

I will introduce the features of near-field devices and present optimization strategies to shape the radiated field while synthesizing the necessary radiating aperture. These capabilities will first be applied to sensing and then to communications.

Next, I will cover the concept of non-diffractive waves, which are solutions to Maxwell’s equations that maintain their profile as they propagate.

I will summarize my current research on non-diffractive beams in the radiative near field.

I will demonstrate how non-diffractive beams can be generated using planar radiating structures, such as metasurfaces and radial line-slot arrays, by exciting cylindrical leaky waves with various field polarizations and bandwidths.

I will also discuss the generation of X-waves, which are non-diffracting pulses.

I will introduce a wideband, circularly polarized radial line-slot array capable of generating X-waves in the millimeter-wave range.

Moreover, we will explore the ability of non-diffractive beams to overcome path loss and navigate obstacles.

To illustrate this, I will present an experimental non-diffractive link utilizing two spline-profiled horn antennas that generate Bessel beams at millimeter waves.

This experimental validation demonstrates the resilience of non-diffractive links to obstructions, paving the way for a novel paradigm in next-generation near-field wireless links.

Over the past decade, non-Hermitian physics and its unique singularities—exceptional points (EPs)—have redefined wave engineering, facilitating breakthroughs in signal generation, routing, and sensing.

My talk starts with reviewing non-Hermitian physics and parity-time (PT) symmetry, demonstrating how the formal similarity between Schrödinger’s and Maxwell’s equations enable electromagnetic systems with unconventional functionalities like unidirectional propagation and chiral dynamics.

I will showcase our recent advancements in the RF and microwave domains, such as EP-based wireless sensors with unprecedented sensitivity, new classes of wideband, lossless and matched non-Hermitian metamaterials exhibiting extreme effective constitutive tensors, super-directive antennas, and entropy-boosted electromagnetic fingerprints for hardware security.

I will also introduce the self-dual absorber-emitter singularity in PT systems and their potential in tailoring laser thresholds and developing ultrasensitive interferometric sensors.
