MEXICO CITY – For every social media post of goals, magic moments and celebratory wefies during the 2026 World Cup, fans at 15 out of the 16 host venues in Mexico, Canada and the United States will ...

Metamaterials progressed greatly due to groundbreaking studies on composite media that show both negative permeability and permittivity at the same time. This study has significantly improved our ...

Abstract: A method for observing acoustic scattering due to reflection/refraction by a fish aggregation and absorption caused by sound propagation through a fish aggregation using autonomous ...

Abstract: This paper presents a new systematic survey of the free-space optical (FSO) system, highlighting its operations and applications in outdoor optical communication underlying its interaction ...

This work achieves the refraction and reflection of flexoelectric-induced directrons at interfaces. With identical physical properties of the media on both sides of the interface, as well as uniform ...

Noise barriers made from trees and other plants can provide a respite from unwanted noise pollution. When strategically placed by a roadway, in a backyard, or in a park, trees help reduce pesky noises ...

We are surrounded by waves. tiny vibrational waves transport sound to our ears. Light waves stimulate the retinas of our eyes. Electromagnetic waves bring radio, television and endless streaming ...

With the success of silicon (Si) solar cell technology, research and development on higher efficiency multijunction solar cells is gaining much attention. Tandem cells with a perovskite top cell and a ...

Negative reflection and negative refraction are exotic phenomena that can be achieved by platforms such as double-negative metamaterial, hyperbolic metamaterial, and phase-discontinuity metasurface.

What is light? The question has fascinated scientists – and painters, poets, writers and anyone who’s ever played with a prism – since classical antiquity. Pythagoras, Euclid and Ptolemy, for example, ...

Bats and moths are embroiled in an evolutionary arms race. Using ultrasonic biosonar, bats detect their insect prey, which in turn deploy diverse strategies to avoid predation. Here, we show that some ...
