Transformation Optics Combined With Line-Integrals for Fast and Efficient Mode Matching Analysis of Waveguide Devices

open access: yesIEEE Journal of Microwaves, 2023
Mode matching method is here applied to waveguide fields calculated in a transformation optics framework. The proposed approach allows to obtain modes in terms of an expansion onto analytical basis functions for a waveguide of general cross-section ...

Measure of straight lines for digital contour analysis [PDF]

open access: yesInternational Journal of Imaging Systems and Technology, 2011
AbstractIn digital geometry, objects such as digital straight lines can be considered as equivalent classes of Euclidean straight lines with respect to a digitization process. This article investigates the analysis of the set of straight lines whose digitization is a given digital straight segment with the help of tools from integral geometry.

Lines, contours and legends [PDF]

open access: yesProgress in Human Geography, 2013
Harnessing the cartographic attributes of line, contour and legend, this paper generates a conceptual vocabulary attentive to the proliferation in everyday mapping. By developing theoretical work that questions the representational certitude of cartography, the paper argues that attention needs to be focused on the non-representational vectors of ...
