Machine learning (ML) models are essential to securing communication networks.However, these models are vulnerable to adversarial examples (AEs), in which malicious inputs are modified by adversaries to produce the desired output.Adversarial training is an effective defense method against such attacks but relies on access to a substantial number of
Weaving is an old technique producing fabric materials by interlocking yarns, which we appreciate every day by wearing textiles.The splendid mechanical features of these Stationery macroscopic interwoven structures such as stability, flexibility, and shape adaptability raised the question whether or not such properties might also be observed on a m
Assuming weakly guiding approximation, we examine orbital angular momentum (OAM) mode mixing on account of ellipticity in a fiber and derive a complete set of analytic expressions for spatial Stationery crosstalk, using scalar perturbation theory that incorporates fully the existing degeneracy between a spatial OAM mode and its degenerate partner c
