A chemically etched D-band waveguide orthomode transducer for CMB measurements

Abstract This study presents a prototype D-band waveguide orthomode transducer (OMT) fabricated using chemically etched brass platelets. This method offers a fast, cost-effective, and scalable approach for producing such devices above 100 GHz, making it well-suited for current an...

Dual-Kinetic Relaxation Spectroscopy for Discrimination of Volatile Organic Mixtures via Finite-Size Surface Gratings

Abstract Discrimination of chemically similar volatile organic compounds (VOCs) in gas mixtures remains a challenge for traditional optical refractive index sensors. In this work, we used a surface holographic grating relaxation technique to monitor the transport kinetics of VOCs...

Expanding Oued Beht: Final Neolithic, Bronze Age, medieval and later discoveries from excavation and survey in 2023

Abstract Oued Beht, Morocco, is emerging as a key site for understanding later prehistory in the northwestern Maghreb. Previous fieldwork by the Oued Beht Archaeological Project (OBAP) in 2022 revealed major evidence of a large and complex focus of activity across the ridge durin...
