Terahertz near field spectroscopy of filled subwavelength sized apertures in thin metal films

Terahertz near-field microspectroscopy

Terahertz near-field measurements of subwavelength antenna structures and metamaterials
This paper demonstrates broadband THZ near-field measurements performed on different types of antennas and meta materials structures, all having sub-wavelength dimensions. The time and frequency dependence of the electric near-field are presented and compared with numerical calcu ...

Influence of the dielectric substrate on the terahertz electric near-field of a hole in a metal

Terahertz Near-field vectorial imaging of subwavelength apertures and Aperture arrays.

Terahertz near-field measaurements of subwavelength antennas

Terahertz near-field measurements of finite and semi infinite rod

Terahertz near-field measurements of subwavelenght, dielectric-filled waveguides

Terahertz Near-Field Measurements of Small Metal Structures

Near-Field THz Imaging and characterization of an Array of Sub-wavelength Circular Apertures

Terahertz near-field measurement of small metal structures

Near-field imaging of subwavelength circular hole arrays at terahertz frequencies
Sub-wavelength, metallic circular aperture arrays were studied in the near-field at terahertz frequencies, using terahertz time-domain spectroscopy (THz-TDS). Two different periodicities were investigated and array subsections were imaged in both the time- and frequency-domain. ...
