Methods of improving the effect of microwaving during the thawing of foodstuffs include the addition of turntables or mode stirrers. The addition of a mode stirrer to the microwave cavity can significantly improve the thawing effect, but there has been little detailed research into the effect of mode stirrers on the thawing process. Therefore, a mode stirrer is set up in the thawing cavity and an ice layer is added to the material in this paper, a more detailed multi-physics field calculation model is developed to study the effect of different parameters of the mode stirrer on the uniformity and efficiency of thawing. The implicit function method is used in the calculation process to solve the problems of large calculation volume and difficult convergence of the mode stirrer thawing simulation. The results of the calculations show that the thawing uniformity tends to decrease and then increase for the adopted cavity size, the height of the mode stirrer has a significant effect on the thawing effect, its speed variation also affects the thawing efficiency but not as much as the height variation, and its length lengthening within a certain range will lead to better thawing uniformity but too long will lead to a decrease in thawing efficiency.","PeriodicalId":363603,"journal":{"name":"2023 5th International Conference on Electronic Engineering and Informatics (EEI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130651679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a non-cooperative LEO satellite orbit determination method using pseudorange with only a single station, which is less affected by interference, occlusion, and weather changes, has low hardware cost, and is free from space-time reference unification and information transmission between receivers. The single station extracts pseudorange observations from signals of opportunity (SOPs), and then the observations are processed by a batch least squares (LS) filter to estimate orbit. Finally, the feasibility of the proposed method is verified by the real experiment, taking Iridium as an example. According to the result, the determined orbit has accuracy comparable to Two-Line Elements (TLE), and the predicted errors of elevation azimuth and Doppler frequency deviation after 3 days are within 0.15°, 2.5°, and 120 Hz, respectively.","PeriodicalId":363603,"journal":{"name":"2023 5th International Conference on Electronic Engineering and Informatics (EEI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114443820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cluster-based channel model conforms to characteristics of the physical channel, and can balance the complexity and accuracy of the model. Therefore, a trajectory prediction model based on Long Short Term Memory (LSTM) for multipath component (MPC) clusters in time-varying millimeter wave channels is proposed. Specifically, after a clustering algorithm used to identify the MPC clusters, Kuhn-munkres (KM) algorithm is applied to identify the moving trajectories of the MPC clusters, and finally LSTM is established to predict and track the moving trajectories of the clusters. The performance of the proposed algorithm is verified by the simulated channel data, and cluster-based channel model of 5G time-varying millimeter wave can be established accurately.","PeriodicalId":363603,"journal":{"name":"2023 5th International Conference on Electronic Engineering and Informatics (EEI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115304818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meanwhile, for air-to-ground missiles, demand of a smaller and more compact configuration leads to a worse electromagnetic environment for antennas of these devices. Some unexpected electromagnetic self-compatibility problems occur, which might significantly affect the performance of the missiles. It is necessary to estimate the coupling condition of antennas in missiles designing progress, and evaluate the self-compatibility situation. In this paper, a simulation model based on finite integration technique is presented. The model comprises an inverted-F antenna and four microstrip antennas. Hexahedron mesh generation is also discussed. The results of the model showed that coupling parameters between adjacent microstrip antennas are much higher the other S parameters, which is up to about -30 dB.
