In order to study a new microwave absorbing properties of single and double layer barium hexaferrite and silika have been investigated in X-band (8.2–12.4 GHz) frequencies. Barium hexaferrite BaFe12O19 was synthesized by ceramic method and Silica SiO2 was prepared from beach sand. Barium hexaferrite and silica with a total thickness of 2 mm, 4 mm, 6 mm, 8 mm and 10 mm, were characterized at room temperature using vector network analyzer (VNA) Rohde‐Schwarz ZVA 67. Reflection loss (RL) of single and double-layer absorbers of barium hexaferrite and silica were calculated using the transmit line theory. The double-layer absorbers exhibit better absorption performances with a stronger microwave absorption and a wider effective absorption bandwidth in comparison with the single-layer absorbers at the same thickness
