However, none of the particles are transported along a longitudinal wave. Instead, they move backwards and forwards between compressions as the wave is transmitted through the medium .

Abstract: Rectangular waveguides loaded by anisotropic metamaterials are analyzed to assess the controllability of transmission characteristics of the involved electromagnetic waves. Dispersion ...

This work examines how a transverse magnetic mode electromagnetic wave propagates in a medium with thirdorder nonlinear and anisotropic electric permittivity. The proposed model is solved using the ...

Millions of Americans face dangerous heat waves this week. Here are essential tips to stay cool and recognize signs of heat-related illnesses.

Beach trips, cookouts and other outdoor activities are in full swing as summer arrives and the first widespread heat wave of 2025 hits the U.S. For many people, summer is their favorite time of year.

Philadelphia got to 101 degrees, breaking the 1923 record of 99 degrees for June 24. In many places, temperatures felt even hotter due to humidity. At least one person died amid the heat wave.

The three planes of motion include coronal (frontal), sagittal (longitudinal), and transverse (axial) planes. These planes involve moving side-to-side, front and back, or rotationally, respectively.

Forecasters said the heat wave is being broken by a “backdoor front,” which will push cooler air across our region from the north and northeast on Thursday and Friday.
