Abstract
At least some aspects of the present disclosure feature a communication device for propagating an electromagnetic wave around a blocking structure. The communication device includes a passive coupling device to capture the electromagnetic wave, and a waveguide electromagnetically coupled to the coupling device. The waveguide is disposed around the blocking structure. The waveguide has a resonance frequency matched with the coupling device. The waveguide is configured to propagate the electromagnetic wave captured by the coupling device.
Claims16
A communication device for propagating an electromagnetic wave around a blocking structure, comprising:
- a passive coupling device disposed proximate to a first side of the blocking structure and configured to capture the electromagnetic wave,
- a transmitter disposed proximate to a second side of the blocking structure, and
- a waveguide electromagnetically coupled to the coupling device and the transmitter and disposed around the blocking structure, the waveguide having a resonance frequency matched with the coupling device, the waveguide configured to propagate the electromagnetic wave captured by the coupling device,
- wherein the transmitter is configured to reradiate the electromagnetic wave.
