近场辐射换热的控制具有重要的实际应用价值。我们提出一种方法来控制近场热辐射之间的两个紧密间隔的机构插入一个悬浮的薄膜。对不同材料组合的掺杂硅和铝（Al）进行了数值模拟。研究表明，两个物体之间的热通量可以增强或抑制取决于薄膜插入物的材料。热通量的大小可以进一步受到膜位置和厚度的影响。这些结果不同于经典的远场辐射传热。
Control of near-field radiative heat transfer is significant due to its practical applications. We propose an approach to control near-field thermal radiation between two closely spaced bodies by inserting a suspended thin film. Numerical simulations are carried out for different material combinations of doped silicon and aluminum (Al). Investigation showed that the heat flux between the two bodies can be either enhanced or suppressed depending on the film insert's material. The heat flux magnitude can be further influenced by the film position and thickness. These results differ from the classic far-field radiative heat transfer.
