Joint WDM and OAM Mode Group Multiplexed Transmission Over Conventional Multimode Fiber Open
To exploit the advantages of multimode fiber (MMF)-based transmission and to improve the overall capacity, transmission of OAM modes over a single wavelength needs to be replaced by multichannel transmission with the proper experimental de…

Interaction of Water Waves with Permeable Barrier using Galerkin Approximation Open
In this paper we analyze the interaction of water waves with a permeable barrier which is slightly perturbed from its vertical position within the framework of linearised water wave theory. The barrier is placed in water of finite depth. T…
