Abstract
An electromagnetic interconnect method and apparatus effects contactless, proximity connections between elements in an electronics system. Data to be communicated between elements in an electronic system are modulated into a carrier signal and transmitted contactlessly by electromagnetic coupling. The electromagnetic coupling may be directly between elements in the system or through an intermediary transmission medium.
