Its elements can separately absorb the electric and magnetic components ?

  1. Jun 3, 2008 #1
    I read about a metamaterial today that can separately absorb the electric and magnetic components of an electromagnetic wave,

    A team of scientists from Boston College and Duke Univ. ... used computer simulations based on prior research findings in the field to design resonators able to couple individually to electric and magnetic fields to successfully absorb all incident radiation, according to their findings.

    Because its elements can separately absorb the electric and magnetic components of an electromagnetic wave, the "perfect metamaterial absorber" created by the researchers can be highly absorptive over a narrow frequency range.

    How is that possible? In an electromagnetic wave, a changing electric field produces a magnetic field and vice versa, or so I thought. Is this article true or is it a science reporting error?
