Researchers have developed new metasurfaces for the arbitrary manipulation of reflected waves, essentially breaking classical reflection law to engineer it at will.

The angles of incidence and angle of reflection are measured between the wave direction and the normal – an imaginary line drawn at 90° to the barrier. The diagram below shows a water wave ...

Time reflections, or spatial reflections, occur when "electromagnetic radiation in the form of light or sound waves hit a mirror or wall, respectively," resulting in a reflection, like a mirror ...

Pressure wave generated by the left ventricle propagates along the arterial tree with manifested phenomena of reflection, dispersion and attenuation. 1, 2 The backward traveling reflection waves ...

The novel distortion matrix approach enables detection of micro-calcifications in breast cancer. These precursors of breast cancer are impossible to detect in the conventional ultrasound image.
