Overview

This research demonstrates effective shielding effectiveness against electromagnetic radiation in nano BZT ceramics, suggesting potential for air traffic control and weather monitoring.

Key Points

  • To synthesize and evaluate the microwave absorption properties of nano BZT ceramics for electromagnetic shielding applications.
  • Synthesis of BZT ceramics using high-energy planetary ball milling
  • Calcination at 1100°C for 2 hours
  • Sintering at 1300°C for 2 hours
  • Analysis using XRD and FESEM to determine structure and grain size
  • Microwave performance evaluated with vector network analyzer across 8.2–12.4 GHz.
  • Ceramic showed a minimum reflection loss of -64.49 dB at 10.93 GHz.
  • Total shielding effectiveness measured at 25.91 dB at 9.58 GHz.
  • Achieved over 90% absorption of electromagnetic waves.
  • Effective shielding bandwidth of 3.6 GHz with permittivity at 11.8 GHz reaching a value of 9.7.
