Popis:	In this article, a patterned honeycomb absorber (PHA) with an embedded frequency-selective surface (FSS) was proposed for broadband applications. The impedance of the FSS embedded in a homogeneous honeycomb absorber (HA) was first analyzed, which suggested that directly combining an FSS with a homogeneous HA was unreliable. Subsequently, a PHA was developed to adjust the input impedance. Using the PHA, an FSS embedded in patterned honeycomb absorber structure with a wide absorption band was developed. The consistency between the simulated and measured results verifies the analysis and design principle. The proposed absorber may be very suitable for various microwave applications owing to its low cost, lightweight, high strength, and environmental friendliness.
