Microwave coupling into a generic object. FDTD simulations and comparison with measurements

摘要: High-resolution (1 mm) FDTD simulations of microwave penetration into a generic missile are presented. The object, being representative large and important class shielded enclosures, consists hollow metallic cylinder with complex internal lossy dielectric structures. Field takes place via thin slots in the shell. It is demonstrated that by carefully controlling measurement setup using an appropriate spatial resolution simulations, very good agreement between measurements achieved, both terms field levels frequency dependence.
