A dual-band quarter-wave plate based on a modified extraordinary transmission hole array is numerically analyzed and experimentally demonstrated at terahertz frequencies. To control independently orthogonal polarizations, ...
Invisibility in a diffusive-light-scattering medium has been recently demonstrated by employing a scattering-cancellation core-shell cloak. Unlike nondiffusive cloaks, such a device can be simultaneously macroscopic, ...
[EN] We propose a very compact metasurface that works as a quarter-wave plate at two
different frequencies, 1 THz and 2.2 THz. The fractional bandwidth of the first band is remarkably
32.2%, beyond the state-of-the-art
[EN] Expanding ideas from microwaves, we demonstrate experimentally a terahertz inductor by using meander-lines in a canonical extraordinary transmission (ET) hole array leading to a strong resonance¿s redshift and an ...
We present a mid-infrared inductor that when applied to an extraordinary transmission hole array produces a strong redshift of the resonant peak accompanied by an unprecedented enlargement of the operation bandwidth. The ...
