Abstract
Objective: This study aims to experimentally and numerically investigate the modulation of electromagnetic wave physical characteristics (transmittance, absorptance, impedance) by strongly an isotropic acoustic materialism in the 2-12 GHz frequency band, and to quantify the influence of material parameters (thickness, density, elastic modulus, an isotropic direction) on wave control performance. Methods: Three types of material units (metal composite, polymer, ceramic reinforced) with thicknesses of 1.5-3 mm and anisotropic directions along X, Y, Z axes were fabricated. Transmittance and absorbance were measured using a vector network analyzer with a WR-90 guideway system. Finite element simulations incorporating acoustic-electromagnetic coupling (strain-induced permittivity modulation) were conducted. Sensitivity analysis was performed by varying thickness (±10%), elastic modulus (±5 GPa), density (±500 kg/m3), and direction angle (±15°). Results: High-frequency absorbance reached 0.91 (metal composite at 9.5 GHz), while low-frequency transmittance remained above 0.70. Thickness and elastic modulus predominantly affected the amplitude and position of high-frequency absorption peaks, whereas density and direction angle primarily regulated low-frequency response, resulting in multi-peak broadband absorption. The deviation between experimental data and finite element simulation was less than 3%. Sensitivity analysis revealed that thickness (±10%) and elastic modulus (±5 GPa) produced the most significant changes in transmittance (0.60-0.91) and absorptance (0.70-0.91). Conclusion: Strongly an isotropic acoustic materialism offer mechanically t unable electromagnetic wave control, with thickness and elastic modulus as key design parameters. These findings provide experimental and theoretical references for high-frequency communication antennas, radar stealth coatings, and broadband absorption devices.
