Broadband Balanced-to-Balanced Filtering Power Divider Using HMSIW-SSPP Transmission Line

Micromachines
In this paper, a novel broadband balanced-to-balanced (BTB) filtering power divider (FPD) utilizing the half-mode substrate-integrated waveguide and spoof surface plasmon polariton (HMSIW-SSPP) hybrid transmission line is introduced.

Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites

Advanced Engineering Materials, EarlyView.
Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

EM simulation of a low-pass filter based on a microstrip defected ground structure using COMSOL [PDF]

, 2012
We perform EM simulations of a lowpass microstrip filter consisting of a crossjunction open stub and two unit sections implemented as defected ground structures (DGS).

Optimization of the Production of Rubber Compounds Using Mathematical Models

Advanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

New Types of Microstrip Filters Using Defected Grounds (Invited Paper)

, 2005
Using Finite Difference Time Domain (FDTD) and microwave circuit simulation tools the use of Defected Ground Structures (DGS) in microstrip low pass, band stop and band pass filters is investigated. The results obtained show that filters with very simple

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Novel Defected Ground Structure Patterns.

, 2006
In recent years, the defected ground structure (DGS) has found numerous applications in the design and improvement of microwave circuits including amplifiers, filters, couplers and oscillators. DGS has the attractive benefits of band rejection, alleviation of the difficulties of fabricating high impedance microstrip lines and size reduction, owing to ...

Toward Knowledge‐Based Workflows: A Semantic Approach to Atomistic Simulations for Mechanical and Thermodynamic Properties

Advanced Engineering Materials, EarlyView.
Knowledge‐based atomistic workflows are presented for mechanical and thermodynamic properties. By coupling modular simulations with ontology‐aligned metadata and provenance, Fe case studies on elastic behavior, defects, thermal properties, and Hall–Petch strengthening reveal how FAIR, queryable, and reusable simulation data can be generated. Mechanical
