Robust Design of Electromagnetic Wave Absorber Using the Taguchi Method

This paper presents a robust design approach that not only optimizes the absorption efficiency of an electromagnetic wave absorber over a wide bandwidth, but also reduces the sensitivity of the optimized performance to a number of hard-to-control variables. The optimizable object is a planar multila...

Zusammenfassung:	This paper presents a robust design approach that not only optimizes the absorption efficiency of an electromagnetic wave absorber over a wide bandwidth, but also reduces the sensitivity of the optimized performance to a number of hard-to-control variables. The optimizable object is a planar multilayer electromagnetic absorber. The important design variables are identified, and the influence of each variable on the performance is analyzed. A robust design of the absorber is realized by employing the signal-to-noise ratio of the absorption efficiency.
