Microwave ovens utilize a mesh on the door that permits visible light while blocking microwaves, leading to inquiries about similar applications for infrared radiation. It is possible to create materials that block infrared radiation while allowing visible light to pass through. The effectiveness of such a mesh is attributed to its function similar to a Faraday cage, which prevents certain wavelengths from penetrating. However, creating a mesh fine enough to block infrared radiation effectively while allowing visible light is deemed impractical. Overall, while there are materials that can achieve this selective blocking, the design of an appropriate mesh remains a significant challenge.
