The authors are retracting this Article.


We were alerted to the possibility that our designed structure is a broadband cross-polarization metamaterial converter, rather than a broadband metamaterial absorber.


We have now performed additional simulations and calculations, confirming that we did not account for cross-polarized reflection in the absorption calculation.


As such, we are unable to support the conclusions regarding design of a broadband metamaterial absorber, because the designed structure exhibits broadband cross-polarization.


All authors agree to the retraction of the Article.
