A Physical Protection System (PPS) protect critical assets and nuclear materials of the Nuclear Power Plant (NPP) from a malicious attack to avoid an unacceptable radioactive consequence. The growing threat terrorism makes NPPs huge challenge. After PPS is developed or updated, it must be evaluated, usually need re-design ensure still meets objectives. Due complexity effectiveness evaluation, a...

In this work, the investigation of wave absorption, phase formation, crystal structure and magnetic properties of SrFe12O19 hexa-ferrites nanoparticles that synthesized by co-precipitation using a microwave heating system and polyaniline-SrFe12O19 was carried out by using a combination of vector network analyser (VNA), X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier tra...
