Overview

Simulation study demonstrates quad-band microwave absorption exceeding 96% with wide-angle stability, indicating high suitability for defense shielding applications.

Key Points

To design and evaluate a multi-band, polarization-insensitive metasurface absorber capable of high electromagnetic absorption across four distinct microwave bands for defense applications.
Conducted full-wave electromagnetic simulations using CST Microwave Studio to optimize symmetric metasurface unit cells across S, C, X, and Ku bands.
Analyzed characteristic impedance, surface current distributions, and electric and magnetic field profiles to characterize the underlying absorption mechanisms.
Constructed an equivalent circuit model using the Advanced Design System to validate the accuracy of numerical simulation results.
Achieved peak absorption rates of 99.8% at 3.5 GHz (S band), 99.9% at 7.1 GHz (C band), 96.9% at 9.4 GHz (X band), and 99.02% at 13.7 GHz (Ku band).
Demonstrated polarization insensitivity across both transverse electric and transverse magnetic modes due to symmetric geometry.
Maintained absorption rates above 80% for oblique incident angles up to 60°.
