Reconfigurable Metamaterial Apparatus and Methods for Microwave Focusing

A method of fabricating a reconfigurable metamaterial apparatus, comprising:

• providing a metamaterial structure capable of focusing incoming radiation, the incoming radiation comprising at least one of a normal incoming radiation and an off-axis incoming radiation, providing the metamaterial structure comprising:
• providing a matrix frame structure;
• and
• providing an array of elements disposed in relation to the matrix frame structure, providing the array comprising providing the array with a refractive index gradient profile, providing the array comprising providing each element with a material having a specific refractive index corresponding to its location in the array, and providing the array comprising providing each element with an alterability feature for facilitating selectively altering its refractive index, providing each element with the alterability feature comprising providing at least one of an interchangeability feature and a tunability feature,
• wherein providing the array comprises providing the array with the refractive index gradient profile that is at least one of tunable and optimizable for at least one parameter of focal stength and frequency, whereby undesirable signals from the incoming radiation are wave-guidable for areal dissipation, and whereby delicate equipment is protectable.
