A method for operating a receiver and a device are provided. In an embodiment of a circuit useful in the system, an AC signal is coupled to a single electrode functioning as an antenna radiating an electric field through a high impedance circuit. On the substrate and on the optical waveguide, a transparent buffer layer is formed to cover the optical waveguide. The glue layer is formed of a non-oxygen-containing material capable of providing an oxygen barrier over the conductive line. Each sub-port adapter performs a checking of the congestion status of all the other sub-ports and acts to stop forwarding received traffic destined for congested sub-ports and holds further received traffic until the sub-ports are reported to be no longer congested. Boron ions may be implanted into the second pocket regions.
