Wireless communication systems play an important role in the intelligent, unmanned, safe production and emergency rescue of coal mine 1. The wireless propagation environment in underground mine is ...
Traditional Finite Difference Time Domain (FDTD) approaches face challenges with increased computational demands and errors as terrain complexity and flight altitude rising. This study introduces the ...
Since its first introduction in 1966, the Finite Difference Time Domain (FDTD) method has been widely used as a tool for solving complex electromagnetic problems. For FDTD, Maxwell’s equations are ...
