Recent years have witnessed a growing interest in reconfigurable antenna systems.Travelling wave antennas (TWAs) and leaky wave antennas Womens skirts (LWAs) are representative examples of structures featuring a great level of flexibility (e.g., straightforward implementation of beam scanning), relatively simple geometrical structure, low profile,
BackgroundThe COVID-19 pandemic has catalyzed a global public response and innovation in clinical study methods.ObjectiveThe COVID-19 Citizen Science study was designed to generate knowledge about participant-reported COVID-19 symptoms, behaviors, and disease occurrence.MethodsCOVID-19 Citizen Science is a longitudinal cohort study launched on Marc
Printing methods such as additive manufacturing (AM) and direct writing (DW) for radio frequency (RF) components including antennas, filters, transmission lines, and interconnects have recently garnered much attention due to the ease of use, efficiency, and low-cost benefits of the AM/DW tools readily available.The quality and performance of these
In a layered and strongly anisotropic superconductor, the hybrid modes provided by the propagation of electromagnetic waves in the matter identify two well-separated energy scales ORG CHIA SEEDS connected to the large in-plane plasma frequency and to the soft out-of-plane Josephson plasmon.Despite wide interest in their detection and manipulation b
