Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing electromagnetic radiation at selected frequencies on a chip or circuit board are limited in their ability to selectively control and generate multiple frequencies efficiently, as they require complex setups and high power consumption.
Innovation Solution
The use of resonant structures on a substrate, excited by a charged particle beam, allows for the selective production of electromagnetic radiation by varying the geometry and spacing of the structures, enabling the generation of multiple frequencies with controlled intensity and bandwidth through deflector systems and beam manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple resonant structures with different geometries are placed on a substrate to generate multiple frequencies, then the versatility and frequency selection capability are improved, but the device complexity increases
Solution Approach 1:
A single charged particle beam source is designed to serve multiple resonant structures simultaneously, allowing one beam to selectively excite different frequencies by adjusting beam parameters such as position, energy, or timing. This multi-functional approach enables frequency selection without requiring separate excitation sources for each resonant structure, thereby reducing overall device complexity while maintaining versatility
Solution Approach 2:
The system employs dynamic control of the charged particle beam parameters (position, energy, timing) to selectively excite different resonant structures. By making the beam parameters adjustable and time-dependent, a single beam can adaptively target different resonant structures to generate different frequencies, reducing the need for multiple static excitation sources and simplifying the device architecture
2Measurement precision
If traditional methods are used to produce electromagnetic radiation at selected frequencies, then the frequency control is achieved, but the power consumption is high
Solution Approach 1:
The system uses periodic excitation of resonant structures with charged particle beams, where each resonant structure is excited only when needed to generate its specific frequency. This periodic, on-demand excitation approach consumes power only during active frequency generation rather than continuously powering multiple independent sources, thereby reducing overall power consumption while maintaining precise frequency control
Solution Approach 2:
The system achieves frequency control by changing parameters of the charged particle beam (such as beam energy, position, or timing) rather than using multiple independent frequency sources. By modulating beam parameters dynamically, the system can selectively excite different resonant structures to produce different frequencies, reducing power consumption compared to traditional methods that would require multiple powered oscillators or sources operating simultaneously

AI summary
We describe an ultra-small resonant structure that produces electromagnetic radiation (e.g., visible light) at selected frequencies that can also be used or formed in conjunction with passive optical structures. The resonant structure can be produced from any conducting material (e.g., metal such as silver or gold). The passive optical structures can be formed from glass, polymer, dielectrics, or any other material sufficiently transparent using conventional patterning, etching and deposition techniques. The passive optical structures can be formed directly on the ultra-small resonant structures, or alternatively on an intermediate structure, or the passive optical structures can be formed in combination with other passive optical structures. The size and dimension of the passive optical structures can be identical with underlying structures, they can merely extend outwardly beyond an exterior shape of the underlying structure, or the passive optical structures can span across a plurality of the underlying structures, including in each instance embodiments with and without the intermediate structures.
