Cascaded Broadband Low‑Frequency Microwave Absorption Covering P‑ to C‑Band in Ultra‑Thin Metamaterials via Synergistic Local‑Field and Loss‑Field Enhancement (IMAGE)
Caption
- A “local field enhancement” strategy based on field-loss co-design, offering a new approach to overcome the performance trade-offs in low-frequency absorption.
- A subwavelength coupled metasurface array is used to replace the traditional reflective layer, breaking the thickness limitation imposed by the quarter-wavelength theory.
- Enabling vertical cascading of absorption performance, moving beyond the constraint of zero transmission in traditional absorbers and opening possibilities for multi-layer design.
