Active Electric Dipole Energy Sources: Transduction via Electric Scalar and Vector Potentials
Sensors, 2022 The creation of electromagnetic energy may be realised by engineering a device with a method of transduction, which allows an external energy source, such as mechanical, chemical, nuclear, etc., to be impressed into the electromagnetic system through a ...

Multi-Channel PWM Heater Control Chip in 0.18 μm High-Voltage CMOS for a Quantum Simulator
IEEE Photonics JournalA circuit to control heating resistors with a pulse-width modulated (PWM) signal for a photonic quantum simulator is introduced. The output voltage is switched on for a changeable specified time and switched off for the rest of the period.

A Geometric Model in 3+1D Space-Time for Electrodynamic Phenomena
Universe, 2022 With the idea to find geometric formulations of particle physics we investigate the predictions of a three-dimensional generalization of the Sine-Gordon model, very close to the Skyrme model and to the Wu-Yang description of Dirac monopoles.

Advanced Science, EarlyView.A self‐powered vibration sensing platform integrates a quasi‐zero‐stiffness piezoelectric harvester, synchronized electric charge extraction, energy management, and wireless ADC acquisition. Ambient vibration is simultaneously harvested as energy and digitized as information, enabling sustained real‐time waveform monitoring without external power.

Symmetry‐Imposed Selection Rules for Excitations of Nontrivial Plasmonic Topologies
Advanced Science, EarlyView.A unified group‐theory selection rule governs the excitation of vectorial nearfield topologies across three plasmonic spin states. Derived from first principles, it predicts spin–orbit vortex splitting and multidimensional nested vortices, confirmed by phase‐resolved in situ measurements.

A Novel Simple Format of Maxwell’s Equations in SI Units
IEEE Access, 2021 In the International System of Units (SI), distinct physical dimensions were assigned to the electric ( $E$ ) and magnetic ( $H$ ) fields as volt-per-meter and ampere-per-meter, respectively. To save the dimensional balance in the standard Maxwell’

Forces on Particles in Time-Varying Magnetic Fields
KONA Powder and Particle Journal, 2017 Electrodynamic sorting is a process that sorts metals based on conductivity, density, and geometry. The process works by inducing electrical eddy currents within particles placed in a time-varying magnetic field.

Maxwell-Chern-Simons-Higgs theory
Acta Polytechnica, 2022 We consider the three dimensional electrodynamics described by a complex scalar field coupled with the U(1) gauge field in the presence of a Maxwell term, a Chern-Simons term and the Higgs potential.

Dual‐Functional Terahertz Manipulation of EuBa2Cu3O7 Superconductors via Cooper Pair Dynamics
Advanced Science, EarlyView.We use a spintronic‐metasurface THz emitter to realize chiral THz generation. Using polarization‐tunable THz pulses, we investigate equilibrium and photoinduced THz responses in a 43 nm thick EuBa2Cu3O7 (EBCO) thin film. The EBCO film achieves 46.81 dB EMI shielding and 113% photoinduced THz modulation with 19.0 ps recovery, enabled by Cooper‐pair ...
