Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coaxial cables are used to carry millimeter waves, then signal transmission is achieved, but the system cost becomes very expensive
Solution Approach 1:
The patent replaces expensive coaxial cables with a cost-effective waveguide system comprising a substrate and dielectric resonators. This substitution maintains signal transmission functionality while dramatically reducing system cost, making millimeter wave communication economically viable for dense deployment architectures.
Solution Approach 2:
The invention changes the transmission medium parameters by using dielectric resonators with specific permittivity values and geometric configurations. This parameter optimization enables efficient millimeter wave propagation through the waveguide structure, achieving performance comparable to coaxial cables at fraction of the cost.
2Reliability
If traditional waveguides are used for millimeter wave transmission, then signal carrying is achieved, but power loss and reflection issues occur
Solution Approach 1:
The patent employs dielectric resonators that resonate at specific millimeter wave frequencies, creating constructive interference patterns that enhance signal propagation. This resonant coupling mechanism minimizes power loss and reflection by matching the impedance characteristics of the waveguide to the transmitted signal, thereby improving transmission efficiency.
Solution Approach 2:
The waveguide system uses composite structures combining low-permittivity substrate materials with high-permittivity dielectric resonators. This composite configuration optimizes electromagnetic field distribution, reduces unwanted reflections, and minimizes power loss through improved impedance matching and field confinement.

AI summary
Techniques are described for a lens containing high dielectric resonators. In one example, a lens comprises a substrate for propagating an electromagnetic wave and a plurality of resonators dispersed throughout the substrate. Each of the plurality of resonators has a diameter selected based at least in part on a wavelength of the electromagnetic wave and is formed of a dielectric material having a resonance frequency selected based at least in part on a frequency of the electromagnetic wave. Each of the plurality of resonators also has a relative permittivity that is greater than a relative permittivity of the substrate. At least two of the plurality of resonators are spaced within the substrate according to a lattice constant that defines a distance between a center of a first one of the resonators and a center of a neighboring second one of the resonators.
