Potential of Commercial Titanium in Electromagnetic Shielding for 5G Frequency Domain

The rapid advancements in telecommunications, medicine, military systems, and electronic devices have led to significant public health concerns regarding electromagnetic pollution. This issue is complex due to the potential for electromagnetic interference (EMI) to cause malfunctions or reduced performance in various electronic devices and systems. Electromagnetic shielding materials are essential for reducing pollution and protecting individuals, devices, and systems. Titanium, with its unique attributes, including enhanced electrical conductivity, durability, environmental sustainability, chemical stability, and superior mechanical properties, is an effective defense against electromagnetic pollution. This study utilizes commercially pure titanium grade 4 (CP Ti Grade 4) due to the complex processes involved in obtaining pure titanium. The study investigates the electromagnetic shielding efficacy of titanium in the 5G frequency bands using a Vector Network Analyzer (VNA), waveguides, and coaxial cables, demonstrating an impressive shielding effectiveness (SE) of approximately 70 dB within the 3.3–6 GHz frequency range
