About
Chinthana Panagamuwa is a leading researcher in electromagnetic dosimetry, specializing in the interaction of radiofrequency (RF) radiation with the human body. His work focuses on how everyday metallic accessories—such as jewellery and spectacles—alter specific absorption rates (SAR) during mobile device use, a critical area for public health and safety standards. In his seminal 2008 study (30 citations), Panagamuwa used FDTD simulations and phantoms to demonstrate that head-worn jewellery can significantly affect energy absorption from face-illuminating devices at popular cellular frequencies. He extended this work in 2009 (10 citations) by examining metallic semi-rimmed spectacles, revealing how eyewear can concentrate SAR in the head from a 900 MHz frontal dipole source, with implications for both children and adults. More recently, his 2017 investigation (6 citations) explored the effects of crumpling deformation on flexible diamond dipole antennas, showing how antenna performance and SAR levels change under realistic usage conditions. Panagamuwa’s research bridges computational modeling and experimental validation, providing essential data for revising safety guidelines. His contributions are particularly valuable for engineers designing wearable and handheld devices, ensuring that everyday accessories are considered in RF exposure assessments.
