Gradient Dielectric Directing Structure for Compact RF Convergence

The patent applies local quality by creating a directing structure with spatially varying dielectric properties. The structure includes a first region with a first dielectric constant and a second region with a second dielectric constant, where the dielectric constant varies continuously or discontinuously across different locations. This gradient dielectric structure enables signal convergence while maintaining a compact form factor, as the varying dielectric properties locally guide and focus the electromagnetic waves without requiring a large overall structure.

The patent employs parameter changes by varying the dielectric constant parameter across the directing structure. The dielectric constant is changed from a uniform value to a gradient distribution, where different regions have different dielectric constants. This parameter variation allows the structure to manipulate electromagnetic wave propagation, achieving signal convergence in a smaller volume by controlling the phase and amplitude distribution of the waves through the graded dielectric medium.

By implementing local quality through spatially varying dielectric constants, the patent enables the directing structure to maintain effective signal convergence in a reduced size. The gradient dielectric distribution creates local phase compensation and wavefront shaping effects that preserve convergence performance while allowing the overall structure to be more compact, thereby increasing integration density.

The patent utilizes composite materials or composite dielectric structures to achieve the desired gradient dielectric constant distribution. By combining different dielectric materials with different permittivity values in a spatially varying arrangement, the structure achieves enhanced signal convergence capability in a compact form, resolving the trade-off between size reduction and performance maintenance.
