RETRACTED: Polarization Characteristics of Electromagnetic Wave Sensing in Confined Space Based on Hybrid Algorithm (Retracted Article)

In order to make better use of electromagnetic waves in communication, navigation, and radar, this invention offers a feature of software to study the polarization of electromagnetic waves in a limited space based on a hybrid algorithm. Using the double Gaussian model, the polarization software model was developed according to vector analysis, and the characteristics of the software at different angles of electromagnetic polarization under the plasma sheath, different peak electron densities, and different collision frequencies were studied in S-band. The results show that at peak electron densities of 10(17)/m(3) and collision frequencies of 0.01 GHz, 0.1 GHz, and 1 GHz, the reverse polarity angles are 53 degrees, 76 degrees and 77 degrees, respectively, and the higher the electron peak densities, the higher the ratio, and the more severe the degradation of the properties: at an angle of 60' to 10(17)/ m(3), 10(18)/m(3), and 10(19)/m(3), the axial ratio of the electron peak density is -1.1.dB,-6.2 dB and-10.1 dB, respectively; the greater the frequency of the electromagnetic wave than the frequency of the collision, the more severe the axial degradation of the electromagnetic wave as the frequency of the electromagnetic wave approaches its frequency corresponding to the maximum electron density. Relationship characteristics were as follows: 2.8 GHz frequency equal to 10(17)/m(3) is the closest to 2.3 GHz electromagnetic frequency, and the axial ratio characteristics deteriorate and are more severe than other conditions; the heterologous medium designed in this paper has simple structure, thin thickness, and easy process preparation, which will have potential applications in radar stealth.
