Extended Composite Right/Left-Handed Transmission Line and Dual-Band Reactance Transformation

Figure 1

A lumped-element model unit cell of an extended CRLH transmission line. {𝑑 is the length of the unit cell. 𝐿₁, 𝐿₂, 𝐿₃, and 𝐿₄ are the inductances in henries/m. 𝐶₁, 𝐶₂, 𝐶₃, and 𝐶₄ are the capacitances in farads/m.}
