Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional two-dimensional electronic circuits face significant challenges with high-frequency signal transmission (>100 GHz) due to radiation and dielectric losses in traditional lines and connectors, leading to increased complexity, cost, and reliability issues as interconnects multiply with circuit complexity, necessitating the development of three-dimensional interconnects and passive components.
Innovation Solution
A three-dimensional dielectric structure comprising a substrate with objects having different dielectric characteristics, distributed according to a spatially varying function, forming a metamaterial that guides, filters, splits, recombines, or amplifies electromagnetic waves, eliminating the distinction between interconnects and devices by treating the system as a single field problem and using objects smaller than the wavelength to achieve desired operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional wires and connectors are used for signal transmission at frequencies above 100 GHz, then the circuit can be constructed using conventional two-dimensional structures, but radiation and dielectric losses increase significantly
Solution Approach 1:
The patent transitions from conventional two-dimensional planar circuits to three-dimensional volumetric structures. By distributing interconnects and components throughout a three-dimensional space rather than confining them to a plane, the invention enables shorter signal paths and reduced interconnect length, directly addressing the exponential increase in losses at frequencies above 100 GHz while managing the inherent complexity through spatial organization
2Adaptability or versatility
If circuit complexity is doubled by adding more units and interconnects, then more functions can be integrated, but the number of interconnects quadruples and reliability decreases
Solution Approach 1:
The patent merges previously separate functional units and interconnects into an integrated three-dimensional metamaterial structure. By embedding interconnects within the volumetric medium and allowing functional units to be distributed throughout the same space, the invention reduces the total number of discrete components and interconnections, thereby improving reliability while maintaining or enhancing functionality
Solution Approach 2:
The three-dimensional metamaterial structure serves multiple functions simultaneously: it acts as both the substrate and the interconnect medium, provides signal transmission paths, and can incorporate functional units. This multi-functionality reduces the need for specialized components and interconnects, decreasing overall system complexity and improving reliability
3Adaptability or versatility
If more interconnects are added to support increased circuit complexity, then more units can be connected, but system cost increases and reliability decreases
Solution Approach 1:
By utilizing three-dimensional space for interconnect routing rather than being constrained to two-dimensional planes, the invention enables more efficient signal paths and reduced interconnect length. This volumetric approach allows multiple signal paths to coexist in the same physical space without requiring additional planar layers, thereby supporting increased interconnect capacity without proportionally increasing system complexity
