Abstract

Technology of microwave absorber has been widely used by over sectors and industries to minimize the effects the radiated signals on the performance of the electronics circuit. Biomass waste material has potential to be used as an alternative way to develop the microwave absorber that used in RF anechoic chamber. This paper investigates the absorption rate performance of durian rind as raw material to develop as a microwave absorbing material for frequency range between 8 GHz to 12 GHz at normal incidents reflection. The absorption rate performances of the developed absorber are compared with the existing commercial absorber in term of absorption characteristics. All the design specifications duplicate the commercial absorber as reference. The measurement results revealed that the best absorption performance of the pure durian rind was 39dB at 10.8GHz and the average absorption obtained 29.5dB which is classified as good performance in absorption.

截形楔形生物质微波榴莲吸收剂吸收率的初步研究

微波吸收技术已被广泛应用于各个部门和行业，以尽量减少辐射信号对电子电路性能的影响。生物质废弃物有潜力作为一种替代材料来开发用于射频消声室的微波吸收器。本文研究了以榴莲皮为原料研制频率在8 GHz ~ 12 GHz的微波吸收材料的吸波性能。将所研制的吸收剂的吸收性能与现有的工业吸收剂的吸收特性进行了比较。所有设计规范均参照商业吸收器。测量结果表明，在10.8GHz时，纯榴莲皮的最佳吸收性能为39dB，平均吸收性能为29.5dB，属于较好的吸收性能。
