Summary:
For imaging of objects smaller than the wavelength, this paper presents a method of employing 60GHz band waveguide-type microscopic aperture probe and the measurement results in the transmission mode. The probe is made of WR-15 waveguide with one end shielded with metal plate, on which a 0.5mm-dia aperture is made. The experimental results to be reported are the spatial resolution measured over a tandem two-slit sample, the sensibility-in-depth measurement against grooves with various depth, and the scanned image of a leaf with parameters of frequency, amplitude and phase.
