【摘要】 研究不同中心频率吸波材料的吸波性能,目前实际工作中,很难找到一种工程实现较简单且全频段吸波性能较好的吸波材料,而多次尝试容易导致材料的浪费和工程效率的下降。为解决上述问题,提出了对不同中心频率和不同阶数的切比雪夫吸波材料建模,并对其吸波特性进行分析对比,在仿真软件Ansoft HFSS进行分析,进而得到最优化的切比雪夫吸波材料,并将应用于工程实践。仿真结果表明,含碳量较高的三阶切比雪夫吸波材料是目前工程实现最容易且全频段吸波性能最理想的。更多还原

【Abstract】 The Absorbing properties of the different orders and different center frequencies of Chebyshev Multilevel Absorbers with the frequencies were investigated.In the practical work,it is hard to find a kind of Chebyshev absorber which has better absorbing performance and is simple for engineering realization.And multiple tries will lead to material waste and the decline in engineering efficiency.In order to solve the problem,we put forward a method to build the models of the Chebyshev Multilevel Absorbers with different center frequencies and different orders using software HFSS,to analyze and compare the absorbing properties of them.And then the Chebyshev Multilevel Absorber was optimized and applied to the practical uses.The experiments show that the three-order Chebyshev Multilevel Absorbers with the high carbon loading is now the most easy to be realized in engineering and has the best absorbing performance with the full frequency range.更多还原
