We report a reconfigurable optical filter chip based on the Si3N4 waveguide platform.Microwave filtering is realized using a device with optical-to-electrical mapping.The filter chip is based on a lattice structure with the dual-ring-coupled Mach-Zehnder interferometers (DR-MZIs) as the basic elements.Both the lattice and ring couplers are tunable,
This work focuses on the preparation of polymer matrix composite specimens by (Hand Lay-Up) method to make bulletproof armor from the unsaturated polyester resin (UP) as a matrix reinforced by Kevlar fibers at different volume fractions Guitar Amp with and without (3%) of Al2O3 powder.The tensile test was performed for these composite specimens whi
Closely related chewing lice in the Philopterus-complex are typically morphologically homogeneous, with the most significant differences often being in the male genitalia.However, in many groups within this complex the male genitalia are reduced and lacking one or more element, with the remaining components often at least partially fused.This is no
Duplex stainless steels are widely used due to their good mechanical properties and corrosion resistance.However, Ziplock Bag they are susceptible to microstructural fragility related to harmful transformations taking place in intermetallic phases, such as the sigma phase.These transformations reduce mechanical properties like toughness and corrosi
Spacer bars in the smart reversible lanes make periodically broadcast of messages to share their local observed traffic information with each other.This aims to help other spacer bars acquire the global traffic information and make consistent movement when separating the flows.However, radio interference and vehicles in the traffic may degrade the
