Innovation Solution
The electromagnetic wave transmission/reception device employs electrodes extending in the x-direction, arranged parallel and perpendicular to each other, with a common lead wire connecting them, applying alternating voltages to induce electromagnetic waves with a resonance frequency, allowing efficient transmission and reception of waves in the z-direction without relying on the waveguide's width direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If waveguide technology is used to guide electromagnetic waves in the width direction, then electromagnetic wave transmission is achieved, but the device cannot transmit or receive electromagnetic waves without a waveguide structure
Solution Approach 1:
The invention extracts the essential function of electromagnetic wave transmission from the waveguide structure by using parallel electrodes arranged in the traveling direction. The waveguide is removed entirely, and only the electrode arrangement remains to generate and receive electromagnetic waves through alternating voltage application, achieving transmission capability without the complex waveguide structure.
Solution Approach 2:
Instead of confining electromagnetic waves within a waveguide structure as in conventional technology, the invention inverts the approach by using exposed parallel electrodes in open space. The electrodes are arranged to generate electromagnetic waves that propagate freely in the width direction without waveguide confinement, enabling transmission and reception in the opposite manner to traditional waveguide technology.
2Productivity
If electrodes are arranged in the width direction of a waveguide, then signal extraction is efficient, but the device cannot receive electromagnetic waves transmitted in the traveling direction from external space
Solution Approach 1:
The parallel electrode arrangement serves multiple functions: it can generate electromagnetic waves when alternating voltage is applied (transmission function) and can receive electromagnetic waves from external space (reception function). This universal design enables the same electrode structure to perform both transmission and reception operations, achieving multi-functionality without requiring separate structures for each purpose.
Solution Approach 2:
The electrode system operates dynamically by switching between transmission and reception modes. During transmission, alternating voltage is applied to generate electromagnetic waves; during reception, the electrodes detect electromagnetic waves from external space. This dynamic operation allows the same structure to adapt between different functional states, achieving both signal extraction efficiency and electromagnetic wave reception capability.
3Reliability
If a waveguide structure is used to confine electromagnetic waves, then noise reduction is achieved, but the device becomes complex and cannot operate without waveguide confinement
Solution Approach 1:
The invention removes the waveguide structure entirely while maintaining signal accuracy through the parallel electrode arrangement. The electrodes are positioned and dimensioned to naturally confine and guide electromagnetic waves between them, achieving signal transmission with less noise without requiring the additional waveguide structure that would increase device complexity.
4Adaptability or versatility
If electrodes are arranged parallel in the traveling direction, then electromagnetic waves can be generated and received, but the voltage application pattern becomes complex to achieve resonance
Solution Approach 1:
Alternating voltage is applied periodically between adjacent electrodes to generate electromagnetic waves at resonance frequency. The periodic voltage application creates standing waves between the parallel electrodes, enabling efficient electromagnetic wave generation and reception. This periodic action simplifies the control mechanism by using a regular, repeating voltage pattern rather than complex variable control.
Solution Approach 2:
The voltage frequency is adjusted to match the resonance frequency determined by the electrode spacing and electromagnetic wave velocity. By changing the voltage frequency parameter to align with the natural resonance of the electrode arrangement, the system achieves efficient electromagnetic wave generation and reception with simplified voltage application control.
