Electromagnetic fields are pervasive in today’s urban environment and under certain circumstances exposure has led to safety hazards that have been reported to cause personal injury. The United States Department of Labor has reported multiple cases of electrical shock on construction ... En savoir plus
Magnetic Resonance Imaging (MRI) is a powerful tool for exploring brain function, offering detailed insights into its structure and physiology. Combining MRI technology with electrophysiological recording systems can enhance comprehension of brain functionality through synergistic ... En savoir plus
Eddy current thermography (ECT) is a non-destructive contact-free method of defect detection in a conductive material combining the electromagnetic induction of eddy currents and thermal imaging. This technique uses an excitation system consisting of an inductor with coil(s) carrying ... En savoir plus
The integrity and safety of reinforced concrete structures are of paramount importance in civil engineering. Detection of flaws in prestressed tendons, especially those buried at critical depths greater than 20 cm, presents a significant challenge. Magnetic flux leakage (MFL) is a non ... En savoir plus
In this work, a 2.8x0.22 μm^2 silicon strip waveguide (n = 3.43 @4.234 μm) on a silica substrate (n = 1.38 @4.234 μm) and a superstrate with n = 1 was designed and evaluated through 2D (i.e., mode analysis), and 3D (i.e., wave propagation) analysis to strengthen the interaction between ...

Lithium niobate (LiNbO3) possesses unique combination of material properties such as: high electro-optic and elasto-optic coefficients and strong piezoelectricity, enabling integration of optical and acoustic functionalities within a single material, paving the way for advanced ... En savoir plus
A magnetic field associated with current carrying coil(s) extends towards infinity, but an analytical model is of finite size. In the finite element analysis (FEA) of electromagnetic systems, open space needs to be modelled as close to reality as possible to get reliable results without ... En savoir plus
The pursuit of artificial magnetism within metamaterials research has long been a focal point. Traditional methods rely on analyzing complex configurations such as arrays of subwavelength particles or split-rings, but unfortunately they fail at subwavelength scales. Revisiting Mie theory ...
