As described above, the scalar Fresnel integral is sufficient to calculate the propagation of the fields through a lens system with a low NA as is used in OCT systems. However, a rigorous solution of Maxwell’s equations is needed in order to couple the fields into the simulation grid of ...
transmitted or scatteredelectron signals. To be specific, the objective lens system in the TEM is used to collect and focus the scattered rays leaving the specimen. It forms adiffraction patternin the back focal plane of the lens or an intermediate image of the specimen in the image plane. ...
We present recent achievements in fabricating a two-dimensional (2D) photonic crystal in the form of a bundle of parallel micro- or nanowires embedded in glass matrix. The method is similar to that of sequential thinning used for fabrication of photonic crystal fibers. We discuss technological iss...
