1Reliability
If a conventional split ring resonator is used, then the device structure is simple, but the resonator suffers from deformation and dimensional errors due to external forces, leading to insufficient performance
Solution Approach 1:
The resonator is divided into multiple conductive members arranged in different layers (first layer, second layer, third layer), with each layer containing specific conductive members that are electrically connected. This segmentation allows the structure to maintain performance stability while distributing the complexity across multiple manageable components rather than using a single complex resonator structure
Solution Approach 2:
The patent transitions from a conventional planar split ring resonator to a three-dimensional multi-layer configuration. Conductive members are positioned in different layers (first layer substantially parallel to reference plane, second layer facing the first layer, third layer facing the second layer) and electrically connected to form a spatial structure that reduces sensitivity to deformation and dimensional errors
2Manufacturing precision
If the split ring resonator is manufactured with standard precision, then manufacturing is easy, but dimensional errors near the split cause performance degradation
Solution Approach 1:
The resonator structure is segmented into multiple conductive members in different layers, where each member can be manufactured and positioned independently. This segmentation allows standard manufacturing processes to be used for each component while the overall structure achieves high dimensional accuracy through the controlled spatial arrangement and electrical connections between layers
Solution Approach 2:
The patent applies different structural configurations to different parts of the resonator. Specific conductive members in different layers are positioned to face each other (e.g., first conductive member in first layer, second conductive member in second layer, third conductive member in third layer) with specific geometric relationships, providing enhanced dimensional stability at critical locations while maintaining ease of manufacture through standardized component design
3Stability of the object's composition
If the resonator structure is made rigid to prevent deformation, then performance stability improves, but the structure becomes more complex and harder to manufacture
Solution Approach 1:
The patent achieves structural stability by distributing conductive members across multiple layers in a three-dimensional configuration rather than using a single rigid planar structure. The first layer, second layer, and third layer are substantially parallel to each other with specific spacing, creating a spatial framework that inherently resists deformation while maintaining a relatively simple component design for each layer
Solution Approach 2:
Multiple conductive members from different layers are electrically connected to function as a unified resonator structure. The first conductive member in the first layer, second conductive member in the second layer, and third conductive member in the third layer are connected through conductive connections, merging the functionality of multiple simpler components into a single stable resonator system

AI summary
A split ring resonator includes a first conductive member having a split ring shape, a second conductive member, and a third conductive member. The second and third conductive members have a split therebetween and are electrically connected with different ends of the first conductive member. The second conductive member includes a first portion belonging to a first layer substantially parallel to a plane to which the first conductive member belongs, a second portion belonging to a second layer substantially parallel to the plane and facing the first layer, and a third portion electrically connecting the first and second portions. The third conductive member includes fourth and fifth portion respectively belonging to the first and second layers, and a sixth portion electrically connecting the fourth and fifth portions. At least parts of the first and fifth portions face each other in a direction substantially perpendicular to the plane.
