Abstract
This work presents a simulation framework for studying the detectability of floating macroplastics
over water surfaces using electromagnetic modeling. The simulation tool combines sea surface generation,
object tracking, and post-processing to replicate realistic conditions in a controlled environment. Implemented in CST Microwave Studio with the Asymptotic Solver, it reproduces scattering behavior for varying wave heights and target configurations. Simulated results show good agreement with measurements performed at Deltares and demonstrate consistent detection trends. The framework enables the exploration of complex and dynamic scenarios beyond experimental limitations, providing a foundation for future remote sensing system optimization.
