A method amplifies a signal on a transmission line. A driver transmits an initial signal on a transmission line, which is overlaid on an Alternating Impedance-Electromagnetic BandGap (AI-EBG) structure (i.e., a reference plane) on a circuit board. The AI-EBG structure induces an alternating change to an impedance in the transmission line. The alternating change to the impedance creates a reflection signal to an initial signal on the transmission line, and the reflection signal and the initial signal combine to create an amplified signal.

1. A method for amplifying a signal on a transmission line, the method comprising: transmitting, by a driver, an initial signal on a transmission line, wherein the transmission line is overlaid on an Alternating Impedance - Electromagnetic BandGap (AI-EBG) structure on a circuit board; andinducing, by the AI-EBG structure, an alternating change to an impedance in the transmission line, wherein the alternating change to the impedance creates a reflection signal to an initial signal on the transmission line, and wherein the reflection signal and the initial signal combine to create an amplified signal. 2. The method of claim 1, wherein the transmission line is in an electronic structure that comprises a conductor layer, an insulation layer adjacent to the conductor layer, an Alternating Impedance Electromagnetic Bandgap (AI-EBG) layer adjacent to the conductor layer, and a signal driver, the transmission line, and a destination device overlaid on the AI-EBG layer, wherein the AI-EBG structure is the AI-EBG layer. 3. The method of claim 2, wherein the AI-EBG layer comprises: an AI-EBG unit cell array of AI-EBG unit cells, wherein each AI-EBG unit cell comprises a metal patch having a first thickness and one or more metal branches having a second thickness, wherein the one or more metal branches extend away from the metal patch, and wherein the first thickness of the metal patch is greater than the second thickness of the one or more metal branches. 4. The method of claim 2, further comprising: connecting a ground to the AI-EBG layer; andconnecting a terminator to the AI-EBG layer and the ground. 5. The method of claim 2, further comprising: connecting a power source to the conductor layer; andelectrically insulating the AI-EBG layer and the insulation layer from the power source by a conducting via through the AI-EBG layer and the insulation layer, wherein the conducting via electrically couples the power source to the signal driver.
