Osteoarthritis: Epidemiology, Diagnosis, and Treatment

MedComm, Volume 7, Issue 7, July 2026.
Osteoarthritis (OA) is a multifactorial degenerative joint disease and a leading cause of disability worldwide. This graphical abstract summarizes the epidemiology, diagnostic strategies, and therapeutic approaches of OA. OA development is driven by aging, metabolic dysregulation, and mechanical stress, leading to progressive joint degeneration ...

Passive Artificial Magnetic Conductor (AMC) Reflector for Far-Field Beam Steering

2024 54th European Microwave Conference (EuMC)
This paper presents a 21×21 passive artificial magnetic conductor (PAMC) surface aimed at achieving fixed beam steering of +30◦ at 10 GHz, featuring a measured beam steering bandwidth ranging from 9.75 GHz to 10.75 GHz. By optimizing its placement relative to the wave source, the PAMC facilitates an additional 60◦ of beam steering in both the azimuth ...
