Dielectric characterization analysis of natural fiber based hybrid composite for microwave absorption in X-band frequency

Emerging issues on electromagnetic interference (EMI) caused by blooming of new electronic gadgets and its implementation in different sectors. Thus, the minimization or to control the effect EMI on electronic devices and the designing of stealth equipment requires special attention for dielectric materials of different blends. To modify the dielectric properties of any material, it requires combination of more than one compatible constituent. The designing of hybrid composite with optimum wt.% contributes good dielectric substrate for interaction with the microwave. The thin layer with 3 mm thickness hybrid composite of banana stem and rice husk dust (BAN/RH) with particle size 150 μm in ratio 50–50 wt.% has been synthesized for X-band testing specimen. The results of microwave properties with reflection loss − 14.01 dB attenuates 96.02% of incident power of EM wave significantly describes the importance of dielectric properties of single layer hybrid composite material in X-band frequency range.
