Abstract

Proper understanding of microwave and split ring resonator is important to design a microwave absorber with split ring resonator (SRR). Therefore, in this project, a method for designing a better reflection loss performance for truncated microwave absorber with split ring resonator has been investigated. Split ring resonator or metamaterial is a type of artificial structure that is not found in the nature. This structure has become an interest among many due to its extraordinary response to electromagnetic waves. The split ring resonator is an example of a metamaterial structure which has the potential to improve the performances of components in microwave without changing the material or with additional radiators. In this thesis, it present the investigation of reflection loss or S11 for the 1x1 truncated microwave absorber with the integration of different number of split ring resonator structure at the truncated absorber for a frequency range between 6 GHz to 15 GHz through design and simulation process by using CST studio Suite 2014 software. Various S11 performances are compared and simulation result for the integration of one double split ring resonator (D-SRR) structure on truncated pyramidal microwave absorber show improvement performance of reflection loss at most of frequency from 6GHz to 15GHz and give the best reflection loss at frequency of 7.39 GHz which is -58.61 dB. Then, the design split ring resonator been simulate for 3 different frequency and modeled using Matlab software. The truncated microwave absorber used in this project is made of agricultural waste, which is rice husk mixed with Urea Formaldehyde as it bonding agent with dielectric constant of 2.9. Thus, this will able to reduce the fabrication cost and more environments friendly.
