Description
Summary:Rice husk is a result of agricultural waste produced from the process of rice milling and water hyacinth is one type of aquatic plant float considered as a weed that can damage the aquatic environment. The carbon content contained in both materials is capable of being an absorber material for electromagnetic waves in the frequency of 4 GHz - 8 GHz. Epoxy is a resin used to produce board rice husk particles and water hyacinth particle board with a ratio of 50%, 60%, and 70%, respectively. The free space measurement method is used to obtain the reflection loss and the transmission loss by using two antenna horns that are connected to the measurement tool Vector Network Analyzer type E5071C. By knowing the amount of absorption value, we can find the value of permittivity material. This value of permittivity is further used to perform simulations with CST software. Simulated and measuring results show relatively small differences.
