摘　　要：设定了六种不同的吸波材料,它们具有不同的相对磁导率的实部（μ＇r）与虚部（μ＇＇r）以及不同的相对介电常数的实部（ε＇r）与虚部（ε＇＇r）.按照Kraus的传输线阻抗转换方程,迭代计算了厚度3mm,1～6层吸波涂层的反射损失在2～18GHz频率范围随频率的变化.计算结果表明,涂层排列方式对反射损失随频率的变化规律有很大影响.Six microwave absorbing materials with respective real and imaginary parts of relative permeability （μ＇r and μ＇＇r） as well as real and imaginary parts of relative dielectric permittivity（ ε＇r and ε＇＇r） were assumed. Reflection loss changes of microwave absorbers having 1 - 6 layers and 3mm thickness with the frequency in the range of 2 - 18 GHz were iteratively computed according to Kraus＇ impedance conversion equation. Computed results show that coating layer arrangement has important effect of reflection loss changes with frequency.
