This review provides a perspective on the recent developments in the transmission of light
through subwavelength apertures in metal films. The main focus is on the phenomenon of …

Considered one of the major fields of photonics of the beginning 21 st century, plasmonics
offers the potential to confine and guide light below the diffraction limit and promises a new …

We show that dye-doped polymers open an interesting route to controlling light at the
nanoscale. Just as for the much better known metal-based plasmonic systems, propagating …

We demonstrate that liquid metals support surface plasmon-polaritons (SPPs) at terahertz
(THz) frequencies, and can thus serve as an attractive material system for a wide variety of …

We demonstrate that multi-walled carbon nanotubes (MWCNTs) are capable of supporting
surface plasmon-polaritons (SPPs) at terahertz (THz) frequencies. To achieve this, we …

We present experimental measurements that show direct determination of the dielectric
properties of various metals relevant to plasmonics. In contrast to traditional measurements …

We demonstrate that conically tapered cylindrical apertures can be used to efficiently
concentrate broadband terahertz (THz) radiation. Keeping the aperture diameter on the …

Novel electroactive metamaterials working in the terahertz (THz) and microwave frequency
ranges are demonstrated utilizing π‐conjugated polymer actuators. Metamaterials are …

The temperature-dependent conductivity of polyaniline emeraldine salt (PAni-ES) was
studied by terahertz (THz) time-domain spectroscopy from 80 to 290 K to investigate …

We have already reported multi-photon excitation of tris (2, 2′-bipyridyl) ruthenium complex
[Ru (bpy) 3 2+] by femtosecond pulse laser with near infrared wavelength as the light …
