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

Using terahertz near field time-domain spectroscopy (THz-TDS), we image subwavelength, cylindrical waveguides (d = 150 mum) loaded with a dielectric material that has a resonance. Time- and frequency-domain near-field images of the individual electric field components are measured as the THz light e...

Description
Summary:Using terahertz near field time-domain spectroscopy (THz-TDS), we image subwavelength, cylindrical waveguides (d = 150 mum) loaded with a dielectric material that has a resonance. Time- and frequency-domain near-field images of the individual electric field components are measured as the THz light emerges from the waveguides.
