Abstract This work has developed and simulated a planar complementary Archimedes-based metamaterial absorber with the goal of its application in refractive index sensing. Unlike designs that employ multiple layers or numerous resonators within single unit cell, our proposed adopts more streamlined approach. It consists three layers, an FR4 dielectric substrate sandwiched between two copper layers. It's important to note absorption characteristics this design are polarization-dependent. polarization dependence arises from asymmetrical resonance behavior observed both x y directions. The exhibits impressive rates at various frequencies, namely 98.5 % f 1 = 8.49 GHz, 77.1 2 8.88 88.7 3 9.3 98.2 4 9.87 99.7 5 10.65 83.4 6 11.58 99.9 7 12.24 GHz.
