Introduction: Metamaterials progressed greatly due to groundbreaking studies on composite media that show both negative permeability and permittivity at the same time. This study has significantly improved our understanding of materials that can surpass the electromagnetic properties of standard substances, thereby transcending the constraints imposed by their intrinsic electromagnetic features. They have attracted considerable interest owing to their remarkable ability to manipulate EM waves through subwavelength structures organized in precise configurations. These materials are famous for their unique electromagnetic characteristics, such as negative index refraction, super-resolution imaging, and perfect absorption. The effective characteristics of metamaterials can be tailored to fulfill particular application needs—like obtaining negative permittivity and permeability—by adjusting the dimensions of a unit cell. With the EM environment becoming more complex, challenges to EM protection are increasing. Microwave absorbers made from metamaterials have come to represent a viable option for stealth technology, as they employ customdesigned structures to absorb electromagnetic waves. As two-dimensional metamaterials, metasurfaces control incident waves precisely through periodic unit designs. Methods: This paper proposes a novel metasurface structure for absorbing oblique incident EM waves. The design composed of double layer metamaterial where the first layer consists of fiber glass which is enforced by epoxy laminate. The second layer is made up of irregular metal patches and linked by metal rings and chip resistors. Results and Discussion: Simulation results show that the proposed metasurface has better absorption capability as compared with existing designs. |
