研究目的
To investigate the directive properties of a monopole nano-antenna formed by a carbon nanotube placed perpendicularly to a metal rectangular screen, and to analyze the radiation patterns and directivity versus the screen sizes.
研究成果
The study provides an asymptotic solution for the 3D vector problem of diffraction of the field of an impedance nanotube monopole on a conducting rectangular screen. It develops fast-active algorithms and software for computing spatial amplitude and polarization patterns. The study finds that the directivity of a monopole with a finite-size screen can significantly exceed that of a monopole with an infinite screen, and it determines the optimal screen sizes for peak radiation.
研究不足
The study is limited to theoretical analysis and software simulation. Practical implementation and experimental validation are not covered.
