Electromagnetic (EM) absorbers are an essential component in the design of high-performance radar and communication systems. Hollow pyramidal absorbers are widely used among different types of EM absorbers due to their excellent absorption characteristics. However, improving their absorption performance remains challenging due to the lack of absorbent materials inside the hollow sections. In recent years, creating slots on the surfaces of hollow pyramidal absorbers has emerged as a promising approach to enhance absorption. Although various types of slots have been tried, their reviews are still lacking. This paper reviews the types of slots used to form slotted hollow pyramidal EM absorbers and elaborates on their effects on absorption performance. It also suggests new approaches that could be used to improve absorption performance. Overall, this review paper offers valuable insights into the design and development of high-performance slotted hollow pyramidal EM absorbers.
