Resumen
We provide experimental evidence of phase resonances in metallic periodic structures in which each
period comprises several subwavelength slits of the same width. We have analyzed and measured
the response of these structures in the millimeter wave regime and show that phase resonances are
characterized by a remarkable minimum in the transmission response, as predicted by numerical

We provide experimental evidence of phase resonances in metallic periodic structures in which each
period comprises several subwavelength slits of the same width. We have analyzed and measured
the response of these structures in the millimeter wave regime and show that phase resonances are
characterized by a remarkable minimum in the transmission response, as predicted by numerical
calculations. We compare experimental with numerical results, obtaining a very good agreement
between them. This experimental confirmation encourages research in compound structures and
their multiple potential applications, such as frequency selective surfaces. [--]
