BAND-GAP COMMUNICATIONS ACROSS A WELL TOOL WITH A MODIFIED EXTERIOR
摘要
A communication system can include a first subsystem of a well tool that can include a first cylindrically shaped band positioned around the first subsystem. The first cylindrically shaped band can be operable to electromagnetically couple with a second cylindrically shaped band. The communication system can also include a second subsystem of the well tool. The second subsystem can include the second cylindrically shaped band positioned around the second subsystem. The communication system can further include an intermediate subsystem positioned between the first subsystem and the second subsystem. The intermediate subsystem can include an insulator positioned coaxially around the intermediate subsystem.
