Extensive use of digital and smartcommunication creates prolong expose of unwanted electromagnetic (EM) radiations. This can not only create malfunctioning of nearby electronic gadgets but also reported that it can affect human health in several ways. Therefore, a suitable microwave absorbing material (MAM) becomes a necessary requirement in the field of stealth and radar technology. In the present work aluminum based hexaferrite phase conjugated with graphene inPoly (Vinyelfluoride) matrix has been tested in X and Ku band for absorption properties. The structural and morphological nature was characterized by X-Ray diffraction (XRD), Field emission-scanning electron microscope (FESEM) and Raman spectra which conforms that 30-100 nm particles are well decorated over graphene sheet. Magnetic force microscopy (MFM) conforms the magnetic nature of composite. Finally, shielding effectiveness (SE) of composite film was studied by using Vector network analyser (VNA) both in X band and Ku band frequency range and found to be more than 30 dB and 40 dB, respectively.
