High-frequency near-field microscopy
WebA high throughput near-field scanning microwave microscope can be implemented. Besides the sharp sensing electrode, a second electrode surrounding the tip is also … According to Abbe’s theory of image formation, developed in 1873, the resolving capability of an optical component is ultimately limited by the spreading out of each image point due to diffraction. Unless the aperture of the optical component is large enough to collect all the diffracted light, the finer aspects of the image will not correspond exactly to the object. The minimum resolution (d) for the optical component is thus limited by its aperture size, and expressed by the Rayleigh criterion:
