Researchers have developed a way to use high-frequency electromagnetic waves to visualize objects that are hidden from view – ...

Millimeter wave radars send fast-moving electromagnetic waves to targets to analyze their movement, position and speed from the waves bounced back. The benefits of millimeter waves are their natural ...

Bit by bit, the physicists have filled the gaps in the electromagnetic spectrum, which runs from X rays at the short end, through light and heat, to miles-long radio waves at the other. One big gap ...

Millimeter-wave spectrum refers to spectrum between 30GHz and 300GHz, whereas existing LTE networks generally work from around 600MHz to 2.5GHz, far lower.

Challenge of millimeter waves. Millimeter wave is the electromagnetic frequency between microwaves and infrared, ranging from 30 to 300 gigahertz. It enables fast communication networks, ...
