Many studies have strongly pointed to the importance of harvesting energy from electromagnetic waves to supply power to sensor networks. Many of these studies, however, have failed either due to the high costs or to difficulties in manufacturing. The aim of this study is to present a very simple metamaterial to harvest energy from microwaves. This structure can absorb energy microwave band with an absorption ratio above 90% by using 400 ohm lumped resistance. The results show a 3.8 GHz perfect absorption band over 90%, and 6.8 GHz absorption band at HPBW Power Beam Width. (C) 2018 The Author.
