Transmission of THz pulses through 3μm apertures: Applications for near-field microscopy

Macfaden, Alexander J.; Reno, J.L.; Brener, Igal B.; Mitrofanov, Oleg

We demonstrate that THz pulses transmitted through small apertures (~λ/100) exhibit strong evanescent components within 1μm of the aperture. Using this effect, we developed subwavelength aperture THz near-field probes that provide 3μm resolution. © 2014 OSA.
