Geometric configuration of device for launching tranverse magnetic waves

A device communicably coupled to a power transmission line and capable of launching transverse electromagnetic waves onto the transmission line, the electromagnetic waves propagating data received from a data source connected to said device, the device comprising:

• a reflector and a coupler adjacent to each other;
• the reflector having a reflector length oriented in a direction generally perpendicular to the transmission line and the coupler having a coupler length oriented in a direction generally perpendicular to the transmission line;
• where
• the length of the coupler is between half the length of the reflector and the length of the reflector.

• where
• the width of the coupler is less than or equal to the width of the reflector.
