From Flat-Optics Concept to Qualified Hardware: Skills Map for the Meta-Optics and Diffractive Optics Workforce
Ingrid Torres, Alex Krasnok
Flat optics is now judged by more than a strong simulation or a single laboratory demonstration. To reach release, a device must survive a chain of handoffs: requirements, model se…
Quantum Magnetometers for Infrastructure Inspection and Monitoring
Muhammad Mahmudul Hasan, Ingrid Torres, Alex Krasnok
Damage in infrastructure is often hidden until it becomes costly or dangerous. Common examples include corrosion under insulation, early fatigue damage in steel, corrosion of embed…
Twist-Tuned Bilayer Metasurface for 3T MRI
Ingrid Torres, Raquel Rodriguez, Robert W. Laird +2
Magnetic resonance imaging (MRI) can see deep inside the body without ionizing radiation, but image quality depends strongly on how well the radio-frequency field is controlled. Pa…
Twist-Tuned Strong Coupling in Sub-GHz Wire Metasurface Bilayers
Ingrid Torres, Alex Krasnok
Twist-angle control offers a bias-free route to reconfigurable metasurfaces, yet its extension to deeply subwavelength resonant platforms at VHF/UHF remains limited. We demonstrate…
A Cryogenic Dielectric Antenna for Wireless Sensing and Interfacing Outside the 10 K Environment
Ingrid Torres, Alex Krasnok
The performance and scalability of cryogenic microwave systems, particularly for quantum processors, are fundamentally limited by the thermal stability and loss of their constituen…
