    Presentation at the conference

    In this report, we will investigate to improve the accuracy of waveform extraction in independent component analysis (ICA). In order to confirm the effectiveness of principal component analysis (PCA), which is a pre-processing for ICA, the result of receiving electromagnetic waves containing a mixture of two components using four-receiving system and performing ICA is presented. The result is...

    Presentation at the conference

    A mathematical model for analyzing electromagnetic and electromechanical transients and periodic modes of a compensated induction motor has been developed. The model is formulated in the normal Cauchy form and adapted for use in computer mathematics software environments. The model provides the ability to take into account the circuit, mode, and parametric features of a compensated induction...

    Presentation at the conference

    This paper presents a comprehensive investigation into the characterization of electromagnetic fields within a Gigahertz Transverse Electromagnetic (GTEM) chamber using a commercially available KSQ1000 comb generator. The measurements provide detailed information on the field uniformity and frequency response across the chamber volume. This data is crucial for ensuring the accuracy and...

    Title:
    Pushing the Limits: Exploring the Dynamic Range in Shielding Effectiveness Measurements

    Abstract:
    This paper examines how window shape and size affect dynamic range of shielding effectiveness measurements in GTEM cell. By analysing the limitations imposed by window geometry, we provide valuable insights for researchers and engineers seeking to enhance the accuracy and...

    Presentation at the conference

    Verifying the level of conducted emissions is very important from the perspective of electromagnetic compatibility. Depending on the environment in which the equipment operates, different allowed emission levels of disturbances are acceptable as a function of frequency. The article presents a research stand, also used for didactic purposes, by the standard PN-EN 55011, which specifies the...
