The 31 papers in the proceedings discuss such aspects as Sierpinski diamond fractal antenna array using a quarter-wave
feed network for wireless applications, a survey of miniaturizing circularly polarized antennas for future wireless communication, neighbor nodes discovery schemes in a wireless sensor network: a comparative performance study, the implementation of a new very large-scale integration architecture for add-multiply operators using a modified booth recording techniques, developing a simple and economic voice control mechanism for operating home appliances, and implementing an efficient and fully automatic magnetic resonance image segmentation through machine learning.
These are the most common type of monopole antennas, specifically, the quarter-wave
The collimated laser beam goes through a polarization beam splitter and a quarter-wave
plate and then be coupled into the optical microscope system via a pellicle beam splitter.
It synthesizes the functionality of a quarter-wave
plate and a focusing lens in an ultrathin metalens.
Most often, polarization control is achieved with a quarter-wave
plate which is one or several layers and the common structure is meander line .
Many novel metasurface devices have been proposed so far, such as planar chiral plates , holography , spin-controlled photonics , wave orbital angular momentum manipulations [13-16], polarization converters and quarter-wave
plates [17,18], flat lens and focusing [19-22], and Huygens metasurfaces [23,24].
Subsequently, the beam is directed toward an experimental configuration composed of two lineal polarizers, a transmission liquid crystal spatial light modulator (TLC-SLM, Sony model LCX038ARA spatial resolution: 1024(H) x 768(V) pixels), and two quarter-wave
As a result of investigations carried out in  significant advantages of MT performed as SICR have revealed as compared to a MT with lumped parameter and compared with known MT of microwave range as quarter-wave
patch and half-mode cavity antennas  are two typical designs of half-size resonator antennas that are suitable for wearable applications.
