kiirgavads
Kiirgavads is a term used in discussions of radiative energy transfer to describe a localized region where electromagnetic radiation is significantly concentrated or enhanced. The concept is typically considered in the context of engineered media, such as metamaterials, photonic crystals, or nanoscale surface structures, where geometric confinement and material responses can modify how radiation is produced, absorbed, or scattered.
In practice, kiirgavads arise from resonant modes, surface polaritons, or altered local density of optical states
Study and measurement rely on radiative transfer theory, fluctuational electrodynamics, near-field heat transfer, and numerical simulations.
Potential applications include more efficient energy harvesting, thermal management in microelectronics, radiative cooling, and improved infrared
