Distance estimation identifies the distance between two machines in wireless network. The Received Signal Strength Indication (RSSI) of Bluetooth can be used to estimate distance between smart devices. The characteristic of Bluetooth RSSI value is different as environments. So, we have tested the relation between distance and Bluetooth RSSI value in several environments, such as indoor hall, me...

Nowadays, electronic products are being used extensively in many fields and applications. The dense population of devices human life has become a challenge for microwave engineers to ensure that their can meet the Electromagnetic Compatibility (EMC) standards. Complex with smaller sizes denser components will be compliance EMC In addition, occurrence non-stationary emission at certain operating...

Abstract—This paper deals with planar scanning technique of electromagnetic (EM) near-field (NF) emitted by electronic printed circuit boards (PCBs) fully in the time-domain (TD). The proposed EM scanning metrology is essentially based on the NF test bench available at the IRSEEM laboratory. It comprises motorized mechanical structures for moving the probe interconnected to electronic measureme...

The technology of flexible cooking surfaces applied to domestic induction heating (IH) appliances offers several advantages that improve the experience users, not only because safety or cleanness, but also due fast and flexibility. These cooktops have more challenging design requirements different mains connections, efficiency requirements, electromagnetic compatibility (EMC) standards, control...

The article investigates the shielding effectiveness (SE) of a metallic enclosure with multilayer composite cover over wide frequency range, from near-field magnetic (1 Hz–1 MHz) to far-field electromagnetic (4–14 GHz). Two enclosures are considered: conductive made aluminum and steel. is trilayer combining thin layer graphene Fe-Ni alloy on either side fiberglass plate. To determine SE these i...

In this paper, common mode (CM) and differential (DM) far-field radiation models of a typical digital inverter with cables are built up to predict electromagnetic field strength analyze characteristics. The CM current model its analyses based on the imbalance difference method. It is found out that voltage between drain source electrodes upper transistor key equivalent interference (EMI). Far-f...

This paper deals with a dichotomous method for the computer-aided search of nonlinear interference sources in complex electromagnetic environment. Compared to the onesignal method, the dichotomous method allows one to carry out a much more faster search (by factor of tens or more). An example of the search process and an estimation of the number of the required analysis cycles as well as descri...
