In this paper, a radar absorbing metamaterial structure is designed, which consists of an upper layer of resistance film and a bottom layer of metal base plate, and the middle dielectric layer is omitted. The thickness of the resistance film is 100 nm, and the thickness of the metal plate is 1mm. The calculation results of CST Microwave Studio 2021 electromagnetic simulation ...

There will be a large amount of ash accumulation in the mineral heating furnace when preparing products, but due to the harsh internal environment of the mineral heating furnace [1], it is difficult to directly observe the situation in the furnace. This project uses the inner cavity imaging system to reconstruct the situation in the furnace through computer three-dimensional, so ...
