Generating Electromagnetic Radiations

Generating Electromagnetic Radiations

The German physicist Heinrich Hertz (1857–1894) was the first to generate and detect certain types of electromagnetic waves in the laboratory. Starting in 1887, he performed a series of experiments that confirmed the existence of electromagnetic waves and verified that they travel at the speed of light. Hertz used an alternating-current RLC (resistor-inductor-capacitor) circuit that resonated at a known frequency and connected it to a loop of wire. High voltages induced across the gap in the...

Applications of EMF Measurements

Applications of EMF Measurements

Electromotive force (EMF) measurements have a broad range of applications in various fields, including chemistry and physics. The electrochemical series, an arrangement of elements in order of their standard electrode potentials, can be determined through EMF measurements. Elements with lower standard potentials can reduce ions of elements with higher standard potentials.The standard cell potential, E°, allows for the calculation of the standard reaction Gibbs energy, ΔG°, and the equilibrium...

Background:

Solar activity, including solar flares and coronal mass ejections, impacts Earth's space environment.
Understanding these effects is crucial for predicting space weather events like geomagnetic storms.
Investigating the influence of solar activity on radio signal propagation, particularly very-low-frequency (VLF) signals, is an active area of research.

Purpose of the Study:

To develop and test an experimental web-based software-defined radio (SDR) monitoring system for indirect solar activity detection.
To assess the system's capability in estimating and potentially predicting space weather events.
To investigate the effect of solar activity on VLF signal propagation.

Main Methods:

Development of a distributed SDR monitoring network.
Comparison of data from the SDR system with established sources like the GOES satellite and Dunksin SuperSID system.
Utilization of Pearson correlation coefficients to analyze data.
Combining signal-to-noise ratios from multiple SDRs to enhance results.

Main Results:

The SDR monitoring system demonstrated high accuracy in detecting solar activity.
Correlation values exceeding 90% were observed between the SDR system and GOES/Dunksin data during solar flares.
Combining signal-to-noise ratios from multiple SDRs further improved accuracy, yielding correlations above 98%.

Conclusions:

The developed web-based SDR system is effective for indirect solar activity detection and monitoring.
Combining data from spatially distributed SDRs significantly enhances measurement accuracy and solar event identification.
The system shows promise for investigating solar activity's impact on VLF signal propagation and predicting space weather events.
