The physics of 3D printing with light

The goal of 3D printing is to realize complex 3D structures by locally adding material in small volume elements called voxels - in contrast to successively subtracting material by etching, milling or machining. This field started with optics-based proposal ...

Toward Metantennas: Metamaterial-Based Antennas for Wireless Communications

Yuanyan Su

Antennas have historically been the most common electromagnetic (EM) technology for wireless communication systems. Antenna as hardware is entirely dependent on the EM properties of the materials used, mostly related to the permittivity and permeability. I ...

Ray-tracing MRT and human thermophysiology model combination for local discomfort prediction

Dolaana Khovalyg, Arnab Chatterjee, Mohamad Rida

Thermal comfort and discomfort based on the local sensation of different body parts have been an important development in thermal comfort studies from the past decade. The human thermophysiology model can be a handy tool to predict local skin and core temp ...

Complementary Metasurfaces for Guiding Electromagnetic Wave

Mohammad Sajjad Mirmoosa

Metasurfaces can be employed for designing waveguides that confine the electromagnetic energy while they are open structures. In this communication, we introduce a new type of such waveguides, formed by two penetrable metasurfaces having complementary isot ...

Modeling of the response function of CdTe detectors for a hard X-ray synthetic diagnostic

Stefano Coda, Joan Decker

The response function of CdTe detectors used in a hard X-ray spectrometer system (HXRS) on the TCV tokamak fusion experiment is modeled based on the measured energy spectra from multiple gamma-ray sources. The response function consists of an asymmetric Ga ...

Study of suprathermal electron dynamics during electron cyclotron current drive using hard x-ray measurements in the TCV tokamak

Stefano Coda, Joan Decker, Jean Arthur Cazabonne

Suprathermal electron dynamics in real and momentum spaces plays an important role in the physics of electron cyclotron current drive (ECCD), in particular for predicting the wave driven current. In the TCV tokamak, a hard x-ray spectroscopy system equippe ...

Bio-optical properties and radiative energy budgets in fed and unfed scleractinian corals (Pocillopora sp.) during thermal bleaching

Niclas Heidelberg Lyndby, Michael Kühl

Corals live in symbiosis with algal dinoflagellates, which can achieve outstanding photosynthetic energy efficiencies in hospite approaching theoretical limits. However, how such photosynthetic efficiency varies with environmental stress remains poorly kno ...

Non-Reciprocal and Topological Wave Phenomena at the Sub-Wavelength Scale

Romain Christophe Rémy Fleury

The utilization of subwavelength resonators, such as small electric dipoles, plasmonic resonators, or objects made of materials with a high dielectric constant, has enabled the manipulation of electromagnetic fields down to the subwavelength regime with sy ...
