All-metallic ε-near-zero (ENZ) lens based on ultra-narrow hollow rectangular waveguides: experimental results
Here we perform numerical and experimental investigation of plano-concave all-metallic ε-near-zero (ENZ) lens with operational frequency f = 144 GHz. The ENZ lens is achieved by stacking an array of narrow hollow rectangular ... -
Analysis of surface-plasmon-like modes under an engineering perspective
In this communication we show how one can exploit equivalent circuits to analyze surface-plasmon-like modes (slit and hole arrays, Sievenpiper mushrooms and coaxial hole arrays) and to propose new designs with outstanding ... -
The beauty of anisotropy in extraordinary transmission fishnet metamaterials
In this work, we explore both numerically and experimentally, the possibility to obtain positive and negative refraction regimes that depend on the wave polarization, exploiting the strong anisotropy of extraordinary ... -
Comportamiento de propagacion electromagnetica en el apilamiento de agujeros sublambda y agujeros propagantes
In this work, we provide more insight on the physics underlying the transmission through subwavelength hole arrays metaprism by comparing it with propagating hole arrays prism. We show the critical role that the size ... -
Lentes metálicas basadas en el fenómeno de transmisión extraordinaria para conseguir índices de refracción negativos
In this communication we report plano-concave and bi-concave metamaterial lenses based on the close stack of subwavelegnth hole arrays. Contrary to what is expected from cut-off holes, an engineered array of holes ... -
Low profile THz periodic leaky-wave antenna
In this work, a 0.566THz flat leaky-wave antenna, consisting of a central λ0/2 slot surrounded by straight parallel wedge corrugations, is numerically and experimentally analyzed. Simulations show a moderately high gain ... -
New regimes to achieve enhanced transmission through subwavelength hole arrays
In this communication we present millimetre- and THz-waves experimental confirmation of enhanced transmission through subwavelength hole arrays with rectangular lattice when the incident electric field is parallel to ... -
Sculpting metals for anomalous transmission phenomena, complex waves and negative refractive metamaterials: underlying physics and applications
In this talk, the potential of controlling the electromagnetic propagation by periodically-textured surfaces is reviewed. It is shown that backward-wave- and slow-wave-propagation, superluminal, effective negative ...
