System having reconfigurable reflectarray structure

A system having a Reconfigurable ReflectArray (RRA) structure, comprising:

• a radiation layer, comprising:
• at least one first P-Intrinsic-N (P-I-N) diode;
• at least one second P-I-N diode;
• a plurality of first reconfigurable reflective units, wherein at least one part of the first reconfigurable reflective units is electrically connected to the at least one first P-I-N diode;
• and
• a plurality of second reconfigurable reflective units, wherein one part of the second reconfigurable reflective units is electrically connected to the at least one second P-I-N diode, and another part of the second reconfigurable reflective units is floating;
• and
• a control layer, comprising:
• at least one first switch element electrically connected to the radiation layer;
• at least one second switch element electrically connected to the radiation layer;
• at least one first control unit electrically connected to the at least one first switch element;
• and
• at least one second control unit electrically connected to the at least one second switch element;
• wherein a number of the first reconfigurable reflective units is different from a number of the at least one first switch element, and a number of the second reconfigurable reflective units is different from a number of the at least one second switch element.
