Sentence examples for em signal from inspiring English sources

However, when applied to EM signal recording in tunnels, the conventional surface EM receivers have a few limitations.

Receivers currently employ single- or dual-polarized antennas, which measure one or two components of the received electromagnetic (EM) signal.

In order to better incorporate and characterise subsoil properties the inclusion of EM signal data (e.g. EM38 or DUALEM-1) may also be appropriate.

In OFF state of diode, FSS-based antenna does not radiate while passes EM signal impinging on its structure in result reduces significantly in-band RCS (up to 15.8 dBmm2) as compared to conventional MPA.

The gradient materials were very advantageous for EMI shielding since the foamed structure at the surface had low dielectric constant and limited the reflection of the EM signal while the presence of highly conductive solid in the middle ensured a high absorption of the electromagnetic radiation.

Interestingly, we observed an electromagnetic (EM) signal simultaneously with the pressure signals, of which OBEM and DPG waveforms are similar (Figs. 5 d) and (f)), thus indicating that the EM signal was also caused by the Chilean tsunami.

It has been shown that each weapon can have a unique fingerprint, which is a set of electromagnetic (EM) signals determined by its size, shape, and physical composition.

These effects seem to be governed by physical factors, too, most evidently electromagnetic (EM) signals generated by the cells themselves8,9, enabling – due to their physical nature – to cross glass or quartz barriers10.

To investigate the problem of electromagnetic (EM) disturbances in the atmosphere from the seismically activated lithosphere, we have formulated two mathematical models of interaction of fields of different physical nature resulting in arising of the low-frequency (from 0.1 to 10 Hz by amplitude of a few hundreds of pT) EM signals in the atmosphere.

This is where additional feedback loops are implemented using additional channels on the mixer: two piezos form two physical feedback loops with the transducers, while two electromagnetic pickups form radio-signal loops using the EM signals produced by the system itself.

A space-borne system, on the other hand, requires high gain because the intensities of received EM signals are inversely proportional to the distance between the EM radiation source and the receiving antenna.
