Due to the absence of turn-to-turn insulation, the electromagnetic behavior of the NI HTS coil during charging is very different from that of a traditional insulated (INS) coil. Many of its problems in engineering applications have not been fully studied. Therefore, the electromagnetic and loss characteristics of the NI HTS multi-pancake coil wound with (RE)Ba2Cu3Ox (REBCO) conductors during the charging process are studied in this article. A lumped equivalent circuit model (LECM) of NI HTS multi-pancake coil is combined with a finite element model (FEM) based on H-formulation. The LECM is used to calculate the current distribution and turn-to-turn loss, and the FEM is used to calculate the magnetization loss of the superconducting layer. The results show that after increasing the difference of the resistance or inductance in the multi-pancake coil, some coils will produce reverse circumferential current and the reflux phenomenon only exists in the early stage of charging. Increasing the number of coil layers will extend the coil charging time. Increasing the charging rate will significantly increase the rising rate and peak value of the coil radial current, making the coil quench risk greater. For the charging loss, the total loss of the multi-pancake coil is several times that of the single-pancake coil. Compared to the INS multi-pancake coil, the NI multi-pancake coil has a smaller magnetization loss rise rate but a larger total charging loss under the same conditions. Therefore, more attention should be paid to the NI multi-pancake coil in the application of superconducting devices.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"61 1","pages":"1-10"},"PeriodicalIF":2.1,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Low-loss propagation is achieved by creating scattering invariant modes (SIMs), which are less affected by the statistical variation of the media than the regular beams used in radio wave communication techniques. The 3-D numerical analysis of the forest calculates the SIMs. A hybrid method based on numerical calculations and the Foldy-Lax approximation is used to obtain fast results in the numerical analysis of the computationally large 3-D problem. This approach makes it possible to create numerous results for building statistics for sensitivity analysis. The robustness of the SIMs is examined by varying the geometry of the vegetation model. The novelty in the current work is the application of a 3-D scattering structure for the investigation of SIM waveform propagation.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"61 1","pages":"1-4"},"PeriodicalIF":2.1,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142912530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These functions allow to represent the sources as equivalent multipoles whose order is associated with a specific spatial decreasing rate. However, this representation is not valid inside the Brillouin sphere, the smallest sphere enclosing the device. We introduce here the use of an alternative model to replace the spherical harmonic functions when the measurements are inside the Brillouin sphere. This representation corresponds to a harmonic basis of equivalent charges on a surface that reproduces the multipolar decomposition of the magnetic field outside the Brillouin sphere while being valid inside. We demonstrate here the ability of this model to identify and extrapolate the field from very close measurements.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"61 1","pages":"1-4"},"PeriodicalIF":2.1,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142912569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
