Near-Field Imaging of Subwavelength Circular Hole Arrays at Terahertz Frequencies

Not Accessible

Your library or personal account may give you access

Abstract

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.
