Theory of diffraction heuristic approaches
WebbA new approximate uniform geometrical theory of diffraction (UTD) solution is obtained for describing the field diffracted by a corner (vertex) in a perfectly conducting plane angular sector which is illuminated by a high-frequency electromagnetic plane wave. This corner diffraction solution is found by a uniform asymptotic reduction of the plane wave … Webb14 apr. 2024 · A novel deep eutectic solvent (DES) and ionic liquid (IL)-modified graphene (G) and graphene oxide (GO) were synthesized and used as effective adsorbents for the preconcentration of three ...

Webb10 apr. 2024 · Airy beams are an intriguing type of non-diffraction wave packet that can exist in one-dimensional (1D) curved orbital plane systems. These beams have gained significant attention due to their unique properties, including non-diffraction, self-healing, and self-bending. In this study, we propose a method for generating high-efficiency and … WebbAn electromagnetic method based on rigorous diffraction theory of gratings is introduced to analyze the modal structure of semiconductor laser cavities. The approach is based on the use of the Fourier Modal Method, the S-matrix algorithm, and the formulation of an eigenvalue problem from which the wave forms and eigenvalues of the modes can be …
