This communication proposes a compact, low-profile patch antenna with vertical polarization.A pair of shorted patches are excited in-phase to achieve the vertical polarisation. The principle is to excite two back-to-back ...

Metasurface refers to a flat interface that has been artificially structured to en able precise and controlled manipulation of electromagnetic waves. It is made up of tiny elements that are arranged periodically or ...

Emotion recognition from electroencephalography (EEG) signals has attracted considerable attention in recent years, as it offers a non-invasive and objective means of assessing emotional processing. In this paper, we ...

An analog-to-digital converter (ADC), which can be either continuous or discrete in nature, is a crucial component of a signal processing system. An oversampling ADC is currently an effective option for data converters ...

With an increase in internet traffic, both long distance fiber networks and short reach interconnections in data centres demand large-capacity optical transceivers. To achieve the proper transmission distances, symbol ...

This study investigates the performance of high quality optical resonator which act as memory cells to store data bits. The theoretical performance thresholds of optical resonator memory cells for use in optical RAM are ...

The light signal in the Radio-over-fiber (RoF) method is modulated by a radio signal to permit long distance communication. In order to boost the capacity of RoF systems, WDM (wavelength division multiplexing) technology ...
