A MEMS Electromagnetic Vibration Energy Harvester with Monolithically Integrated NdFeB Micromagnets

Advanced Materials Technologies, EarlyView.
50µm thick sputtered arrays of NdFeB micromagnets are directly integrated into a functional MEMS in‐plane electromagnetic vibration energy harvester. A combination of analytical modeling and numerical simulations guided the design of the magnet arrays and ad‐hoc coil, to produce a high transduction factor.

From higher-spin gauge interactions to Compton amplitudes for root-Kerr

Journal of High Energy Physics
We develop massive higher-spin theory as a framework for describing dynamics of rotating compact objects, such as Kerr black holes. In this paper, we explore gauge interactions up to quartic order and corresponding Compton amplitudes of higher-spin ...

Frequency‐Selective Terahertz Wave Amplification by a Time Boundary in Huygens' Metasurface

Advanced Optical Materials, EarlyView.
In a free‐standing all‐dielectric Huygens' metasurface, ultrafast pulsed laser excitation is used to establish the time boundary for a coherent modulation to the electric and magnetic polarizability in the adiabatic limit. Amplification of THz waves at frequencies that can be continuously tuned have been achieved, showing an effective energy gain up to

Plane electromagnetic wave in PEMC [PDF]

arXiv, 2005
Plane electromagnetic wave propagating in perfect electromagnetic conductor (PEMC) is considered. Its wave number has no connection with the frequency. An interface is introduced between an ordinary isotropic medium and PEMC. The wave in PEMC is matched to plane electromagnetic wave incident normally on the interface from the ordinary medium and ...

Helical Ladder Oligomers Exhibit Amplified Circularly Polarized Emission

Advanced Optical Materials, EarlyView.
The discovery that a multi‐helicene system based on a series of annulated [6]helicenes and perylenediimides, exhibits larger‐than‐linear amplification of glum with helicene length is described. It is also observed large enhanced fluorescent quantum yields and large extinction coefficients for this length series.
