Simulation and design for stratified iron fiber absorbing materials

An absorbing method utilising iron fiber fillings produces a microwave-absorbing material with an ability to perform intelligently. The materialʹs reflectivity is dependent on its permeativity, permmitivity being the angles between the oriented fibers in the layers, thickness of the layers and other parameters. Based on electromagnetic field theories and using the transmission matrix method, this paper presents a formula for the evaluation of the field reflectivity of stratified oriented iron fiber sheets with a conductor underlay. The simulating and tracking calculations relating to the incident electromagnetic waves in a multi-medium are realized based on given electromagnetic parameters. The results produced by The material performance optimization process are visual. The numerical results show that the calculation, incorporating multiple parameters, can formulate the relationship between reflectivity and other parameters rapidly, providing an academic base for absorbing-material preparation.
