Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If conventional conductor and dielectric materials are used, then the microcircuit structure is simple and easy to manufacture, but signal delays increase and synchronization is lost at high clock speeds
Solution Approach 1:
The patent replaces the conventional electrical signal transmission through metal conductors with electromagnetic wave propagation through dielectric layers. This substitution transforms the signal carrier from electrical current in conductors to electromagnetic waves in dielectric media, enabling faster signal propagation without the limitations of conductor delay and synchronization issues.
Solution Approach 2:
The patent changes the fundamental parameter of signal transmission from electrical conduction to electromagnetic wave propagation. By altering the signal carrier type and transmission medium properties, the system achieves higher speeds while maintaining manufacturing feasibility through standard semiconductor processing techniques.
2Loss of time
If conductor material is changed from aluminum to copper, then signal delay is reduced, but manufacturing complexity and processing requirements increase
Solution Approach 1:
The patent eliminates the need for specialized conductor materials like copper by replacing the electrical conduction mechanism with electromagnetic wave propagation. This substitution removes the requirement for complex copper processing while achieving reduced signal delay through the inherent properties of dielectric waveguides.
3Loss of time
If dielectric constant of dielectric layers is reduced, then capacitance between conductor and dielectric layer is reduced, but signal dispersion through inhomogeneous media increases
Solution Approach 1:
The patent replaces electrical signal transmission through conductors with electromagnetic wave propagation through dielectric layers. This substitution eliminates the conductor-dielectric interface that causes capacitance effects and signal dispersion, as the electromagnetic waves propagate through the bulk dielectric material without conductor boundaries.
Solution Approach 2:
The patent utilizes the homogeneous nature of dielectric layers to guide electromagnetic wave propagation. By ensuring uniform dielectric properties throughout the waveguide layer, the system maintains signal integrity and prevents dispersion that would occur at conductor-dielectric interfaces in conventional structures.

AI summary
A device includes a waveguide layer formed on a substrate. An ultra-small resonant structure emits electromagnetic radiation (EMR) in the waveguide layer. One or more circuits are formed on the waveguide layer and each operatively connected thereto to receive the EMR emitted by the ultra-small resonant structure. The waveguide layer may be transparent at wavelengths corresponding to wavelengths of the EMR emitted by the ultra-small resonant structure. The EMR may be visible light and may encode a data signal such as a clock signal.
