“…Hence, there is a requirement to develop new techniques for the design of polarization insensitive multiband and broadband absorbers which is observed missing in this study of comment on the proposed design.

The cross polarization analysis of the proposed design done in "Comment on 'A Wideband Wide-angle Ultra-thin Metamaterial Microwave Absorber" is similar to studies already conducted in [1,2]. However, this analysis reveals that the design provides quite low absorption due to its diagonally symmetric geometry, but such various design configurations reported by different researchers [3][4][5][6][7][8][9] create the path to understand the importance of the requirement of polarization insensitive wideband/broadband metamaterial absorbers. Further, this importance enhances the in depth analysis of polarization sensitive multiband and wideband absorbers (so called) that are designed based on the studies and findings done at that time. Moreover, the very first perfect metamaterial absorber design reported in [7] is polarization sensitive, but it spawned great interest of researchers at the time due to its potential applications, and therefore, it becomes the motivation for today's absorbers. Similarly, the dual-band designs reported in [8,9] are also polarization sensitive, but they give an idea to design multiband and wideband metamaterial absorbers. Hence, there is a requirement to develop new techniques for the design of polarization insensitive multiband and broadband absorbers which is observed missing in this study of comment on the proposed design. Moreover, it also proves that the proposed design is a good metamaterial based wideband rotator which makes it useful for other potential applications such as spatial filters [10,11] and radomes [12].Thus, it is concluded that the design of monolayer polarization insensitive metamaterial based multiband and wideband microwave absorbers is still a challenge, and the readers should take this as an opportunity to improve the existing polarization sensitive designs or develop some techniques to reduce cross polarization effects as reported in [13] rather than simply proving that which one is an absorber or not as reported in [1,2,14].

“…The Wilkinson power dividers are designed on the RF-35 substrate. The resonance mode is maintained even though the substrate integrated waveguide becomes a half-mode substrate integrated waveguide (HMSIW) or a quarter-mode substrate integrated waveguide (QMSIW) [18][19][20][21][22][23][24][25][26][27].

A phased array system with quasi-hemispherical region scanning performance is proposed. The proposed system is implemented using triangular substrate integrated waveguide (SIW) elements with short ends, which have a quasi-hemispherical beam pattern. Shorted vias at the vertex and side of the triangular patch were made to act as SIW antennas, generating magnetic currents characterized by radiating to a quasi-hemisphere pattern. The measured results show that the prototype planar phased array has scanning ranges of about 160 • in both horizontal and vertical planes, and about 170 • in both two diagonal direction planes, with 5 dB gain fluctuation. key words: wide-angle scanning, planar arrays, phased arrays, quasihemispherical beam pattern Classification: Microwave and millimeter-wave devices, circuits, and modules This article has been accepted and published on J-STAGE in advance of copyediting. Content is final as presented.

“…In recent years, there are an increasing number of FSS designs with high selectivity characteristics following the development of substrate integrated waveguide (SIW) technology [11][12][13][14]. For the inherent high quality factor (Q-factor) of the SIW cavity, the FSSs based on SIW (SIW-FSSs) can achieve good frequency selectivity characteristics.…”

“…In [11], Luo et al presented lots of SIW-FSS for the first time, and an SIW-FSS with polarization rotation is presented by Simone et al and Zuo et al in [12,13]. To reduce the cell size, quarter-mode substrate integrated waveguide (QMSIW) cavity is used in [14]. All the same, SIW-FSS or QMSIW-FSS is difficult to reduce the size further.…”

Abstract-A wideband frequency selective surface (FSS) with a sharp band edge is proposed. The periodic cell includes a mushroom-like cavity and four L-type slots etched on the top and bottom conductor claddings of the cavity. The measured results show that the proposed FSS operates at X band with a 12.5% bandwidth (7.85-8.90 GHz), in which the insertion loss is less than 3 dB. Comparing with the FSSs based on substrate integrated waveguide cavity, the proposed FSS not only realizes high selectivity, but also realizes a 55.8% reduction in cell size.
