摘要：

This letter introduces a conformal multifunctional Terahertz Metamaterial-Resonator (TMR) that achieves ultra-wideband absorption (4.6-9.3 THz) without extra circuit components. Its isotropic design ensures angular and polarization stability on flat and curved surfaces. Utilizing phase-changing Vanadium Oxide (VO2), the TMR reconfigures as an absorber, reflector, or transmissive structure, with simulation results aligning with the derived equivalent circuit model.
