Metamaterial-based absorbers have recently attracted considerable attention. Unfortunately, there are some differences between measurements and simulations, the underlying mechanisms for these behaviors have not yet been unraveled. A detailed understanding of the origin of these discrepancies is essential for optimizing the metamaterial absorber. Herein, we first study the influence of parameters on the performance of the absorber. The influence of parameters on the absorption performance can be summarized as three points. Immediately following, the practicability of the investigation is discussed by choosing two typical examples. Finally, according to the frequency-dependent parameters, three design strategies are summarized to obtain broadband absorbers..
