Semiconductor material bends light

News
According to United Press International, U.S. scientists have found an easy-to-produce semiconductor material can bend light in the opposite direction from all naturally occurring materials.
According to United Press International, U.S. scientists have found an easy-to-produce semiconductor material can bend light in the opposite direction from all naturally occurring materials.

A Princeton University-led research team said material with such a property might contribute to significant advances in many areas, including high-speed communications, medical diagnostics and detection of terrorist threats.

Researchers said the substance is in a relatively new class of materials called ‘metamaterials' that are made from traditional substances, such as metals or semiconductors, arranged in very small alternating patterns that modify their collective properties. That approach enables metamaterials to manipulate light in ways that cannot be accomplished by normal materials, scientists said.
