Electromagnetic Characteristics of Carbon Fiber Based Microwave Absorber for Fixed Mobile FSS Band

This paper presents the simulation characteristics of the low-cost woven carbon fiber-based microwave absorber for fixed mobile fixed satellite service (FSS) band application. A 4x4 thin twill fabric unit cell is simulated in HFSS to investigate its absorbing property to exploit its potential use as an absorber. Starting from single layer up to four layers of the structure is simulated and the effect of thickness of the fabric on the amount of absorbance as well as on bandwidth of the absorbance are studied. The proposed scheme is suitable for EMI/EMC application in the high frequency circuits for mitigating the radiated emission for circuits used in fixed mobile FSS band.
