Microwave absorber based on biocomposites derived from agricultural wastes with reinforcement of poly lactic acid
Published 2021“…Due to fabrication error, the MA thickness is different form the simulation although their plots show same trends except for the shifted resonant frequency. A fine-tune simulation shows that the fabricated MA consider to have ’ = 2.46 and tan = 0.12 and frequency at 8.17 GHz where the corresponding AR is 32%, FBW is 26.8% and FOM is 3.2% per unit mm which is close to the fabricated results. …”
