Design of THz metasurfaces for thin-film sensing
El trabajo propuesto trata sobre el diseño de metasuperficies en la banda de los terahercios para su uso como sensores de películas muy delgadas. En primer lugar, se ha llevado a cabo un estudio profundo ... -
Experimental demonstration of deeply subwavelength dielectric sensing with epsilon-near-zero (ENZ) waveguides
In this Letter, an all metallic sensor based on ε-near-zero (ENZ) metamaterials is studied both numerically and experimentally when working at microwave frequencies. To emulate an ENZ medium, a sensor is made by using a ... -
Labyrinth metasurface absorber for ultra-high-sensitivity terahertz thin film sensing
In this work, a labyrinth metasurface sensor operating at the low‐frequency edge of the THz band is presented. Its intricate shape leads to a high electric field confinement on the surface of the structure, resulting in ... -
On the performance of an ENZ-based sensor using transmission line theory and effective medium approach
In this paper we perform an in-depth theoretical studyofa sensing platform based on epsilon-near- zero (ENZ) metamaterials. The structure proposed for sensing is a narrow metallic waveguide channel. An equivalent circuit ... -
THz sensing with anomalous extraordinary optical transmission hole arrays
Subwavelength hole array (HA) metasurfaces support the so-called extraordinary optical transmission (EOT) resonance that has already been exploited for sensing. In this work, we demonstrate the superior performance of a ... -
Tripod-loop metasurfaces for terahertz-sensing applications: a comparison
The high electric field intensity achieved on the surface of sensors based on metasurfaces (metasensors) makes them an excellent alternative for sensing applications where the volume of the sample to be identified is tiny ...
