Exterior Radiation

Exterior radiation, the unwanted emission of energy from a source intended for localized application, is a significant challenge across various fields. Current research focuses on minimizing this unwanted radiation in applications like sound field synthesis and active noise control, employing optimization algorithms such as Riemannian optimization and nature-inspired methods (e.g., ant colony optimization) to control energy distribution and suppress side lobes. These advancements aim to improve the efficiency and precision of technologies relying on controlled energy emission, impacting fields ranging from acoustics and audio engineering to antenna design and signal processing.
