Abstract:
1. An apparatus for receiving and transmitting signals, comprising: a positive refractive index medium; a negative refractive index medium having a first side and a second side disposed in the positive refractive index medium; a plurality of first transmission lines, each first transmission line having a first end extending toward the first side of the negative refractive index medium; and a plurality of second transmission lines, each second transmission line having a second end extending toward the second side of the negative refractive index medium, wherein a plurality of electromagnetic signals, each electromagnetic signal travelling in a first direction, enters the positive refractive index medium and travels along the plurality of first transmissions lines and exits into the first side of the negative refractive index medium, passes through the negative refractive index medium and exits through the second side of the negative refractive index medium into the positive refractive index medium along a first one of the plurality of second transmission lines.
