This work examines the feasibility of using metamaterials to direct radiation. The limits of required index of refraction and the required material depth are explored using MATLAB simulations. A wedge of connected S-shape metamaterial is chosen and simulated in CST Microwave Studio. The incident radiation is Transverse Magnetic (TM) and negative deflection is achieved. The S-shape wedge is adjusted in small ways, and a specific wedge is chosen for further study. The S-shape metamaterial wedge is then adjusted by adding lumped elements of capacitance throughout the structure. A beam through this adjustable material is deflected -76° to +580 by adding 0pF to 6pF additional capacitance. The deflection is not monotonic, but most pronounced between 0.lpF and 0.8pF. The deflection is discussed, as well as the regions of strongest signal power.

<Abstract>This work examines the feasibility of using metamaterials to direct radiation. The limits of required index of refraction and the required material depth are explored using MATLAB simulations. A wedge of connected S-shape metamaterial is chosen and simulated in CST Microwave Studio. The incident radiation is Transverse Magnetic (TM) and negative deflection is achieved. The S-shape wedge is adjusted in small ways, and a specific wedge is chosen for further study. The S-shape metamaterial wedge is then adjusted by adding lumped elements of capacitance throughout the structure. A beam through this adjustable material is deflected -76° to +580 by adding 0pF to 6pF additional capacitance. The deflection is not monotonic, but most pronounced between 0.lpF and 0.8pF. The deflection is discussed, as well as the regions of strongest signal power.</Abstract>
