Claim 0:
1. A coupling device, comprising:
a high-order mode direct coupling module configured to couple a first electromagnetic wave from a transmitter to form a second electromagnetic wave propagating in a preset high-order guided wave mode;
a mode converting and filtering module configured to convert the second electromagnetic wave into a third electromagnetic wave propagating in a superposition of a plurality of guided wave modes including a preset low-order guided wave mode and at least one high-order guided wave mode, and to filter out the high-order guided wave mode in the third electromagnetic wave to obtain a fourth electromagnetic wave propagating in the preset low-order guided wave mode; and
a mode matching module configured to convert the fourth electromagnetic wave into a fifth electromagnetic wave propagating along a surface of an open wire in a target guided wave mode.
