| Abstract | ||
| Composite RAM Material Single on Multilayer at x- Band Frequency (8-12.5 GHZ) Such as BaCoxTix Fe12-2x O19Prepared in Our Work For Different Values of x (0.25 , 0.5 , 0.7 , 0.9 ,). Reflection Loss (-dB)AND TANGENT Loss TAN Ɛ , TAN µ were Measured using Wave Guide System. Powder Technology used to Prepare the Above Ferrite at 1350 co for 12 hr as Sintering Temperature to be as Filler for Composite Absorber using Epoxy Resin as Amatrix. We Found in our Work that Barium Ferrite at Microwave Frequencies and That We Can Prepare Thin Layer Absorber Less Than 1mm Think RAMMaterials. We Found Also That at x=0.5 , 0.7 , 0.9 We Can Cover The Most Frequencie of the x – Band With Reflection Loss Larger Than (-20db) . So We Can Prepare Four Larger With Less Than 4mm Thickness With Band Width (3.5 GHZ ). | ||
