Abstract: Methods for analysis of the magnetic grain using a software program effectively and accurately by improving the magnetic grain boundary contrast from an image prior to analyzing the grain size with an imaging analysis program. A method for automated grain size analysis includes obtaining a SEM electronic image of a magnetic material composed of a plurality of grains and modifying the image by smoothing the image, removing high spatial and low spatial frequencies from the image, improving contrast of the image, pixelating the image, processing the image to a binary image, and clearing outer edges of the binary image to remove at least incomplete grains to generate grain size data from the image.

Abstract: The present disclosure refers to a printed circuit for integration in a smart card, wherein the printed circuit comprises a printed circuit substrate of dielectric material, an antenna having a resonance frequency, one or more contact pads forming an external contact pattern, and at least one surface mount (SMD) capacitor connected to the antenna so as to adjust its resonance frequency, in order to match a predefined resonance frequency, for instance a resonance frequency comprised within the range defined in ISO 14443 standards. The present disclosure also refers to a module comprising the above-indicated printed circuit and an IC chip and to a corresponding smart card.
