dc.description.abstractIn this study, the traditional mixed oxide process was used to create ZnNb2O6 -chopped strands composites. The single phase compound with the chemical formula ZnNb2O6 was generated after sintering at 1100 degrees C for 4 h. For the structural investigation, various quantities of ZnNb2O6-chopped strands were generated. X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) were carried out for the structural analysis, which indicated that the second phase did not form in ZnNb2O6. Additionally, the ZnNb2O6-strands composites were manufactured by hot pressing using the compositions of ZnNb2O6-chopped strands in various proportions and epoxy. The ZnNb2O6-chopped strands compound formed in various weights, and epoxy resin were used to fabricate microwave shielding effectiveness composites. Utilizing a network analyzer, the microwave shielding effect of ZnNb2O6-chopped strands composites was investigated in a range of 6.5-18 GHz. At a thickness of 1.5 mm, a minimum of -51.32 dB shielding effectiveness value was achieved at 6.75 GHz. The ZnNb2O6-chopped strands compounds were produced as composite and their features were characterized for shielding effectivacy. The content of components in the samples may be managed for the larger and needed frequency bands to change the microwave shielding performance.
