Abstract

Agricultural waste material is produced as a result of an agricultural activity. Water hyacinth is made up of natural compounds. It mainly consists of carbon about 32-35 % by weight. This research has emphasized its eco-friendly nature. Also it has high microwave absorption properties. Samples are fabricated using an agent with water hyacinth to fabricate the proposed absorber. Its performance is determined in terms of its reflection coefficients. It results are compared with that of the commercial microwave absorbers in the frequency range of 0-20 GHz.
