Call-for-Papers for PIER Special IssuesBeing an open access on-line journal, PIER gives great prominence to special issues that draw together significant and emerging works to promote key advances on specific topics. The special issues are devoted to timely, relevant, and cutting-edge research and aim to provide a unique platform for researchers interested in selected topics.We are now calling for papers for the following PIER Spe The 43rd PIERS in Hangzhou, CHINA21 - 25, November 2021 (from Sunday to Thursday)--- Where microwave and lightwave communities meetHybrid PIERS: Onsite + Web AccessImportant Dates：20 June, 2021 --- Abstract Submission Deadline20 August, 2021 --- Pre-registration Deadline25 August, 2021 --- Full-length Paper Submission Deadline20 September, 2021 --- Preliminary Program5 October, 2021 --- Advance Program20 October, 2021 --- Final ProgramQuick Links：To organize a Special Session, please fill out this PIERS Survey Form.Online Abstract Submission  Join Us in this Harvest Season - Onsite + Web Access Night West Lake - PIERS 2021 Hangzhou, CHINA PIERS 2021, Hangzhou, CHINA Late autumn - PIERS 2021 Hangzhou, CHINA West Lake - Hangzhou, CHINA PIER Journals are a family of journals supported by the PhotonIcs and Electromagnetics Research Symposium (PIERS), which has become a major symposium in the area related to photonics and electromagnetics. The scope includes all aspects of electromagnetic theory plus its wide-ranging applications. Hence, it includes topics motivated by mathematics, sciences as well as topics inspired by advanced technologies. The spectrum ranges from very low frequencies to ultra-violet frequencies. The length scale spans from nanometer length scale to kilometer length scale. The physics covers the classical regime as well as the quantum regime. Superscattering of Light in Refractive-Index Near-Zero Environments Chan Wang, Chao Qian, Hao Hu, Lian Shen, Zuo Jia Wang, Huaping Wang, Zhiwei Xu, Baile Zhang, Hongsheng Chen, and Xiao Lin ISSN: 1070-4698 2021-06-03 Surface Electromagnetic Waves at Gradual Interfaces Between Lossy Media Igor I. Smolyaninov A low loss propagating electromagnetic wave is shown to exist at a gradual interface between two lossy conductive media. Such a surface wave may be guided by a seafloor-seawater interface and it may be used in radio communication and imaging underwater. It should allow communication distances of the order of 500 m at 10 kHz along a sandy seabed. Similar surface waves may also be guided by various tissue boundaries inside a human body. For example, such surface wave solutions may exist at planar interfaces between skull bones and grey matter inside a human head at 6 GHz.....2021-05-12A High Gain Inverse Concentric Yagi Director Antenna for 5G Millimetre-Wave and Satellite CommunicationRaqeebur Rehman, Javaid A. Sheikh, Khurshed A. Shah, and Ghulam Mohiuddin Bhat A novel high gain two port planar antenna for 5G millimetre-wave and satellite band is presented. The proposed antenna besides working in the millimetre-wave range has an added feature to work for the satellite X-band as well. The antenna has a miniaturised low-cost planar geometry having the dimensions of 1.83λ x 1.83λ x 0.07λ at 27.5 GHz, designed and fabricated on a Rogers RT/duroid substrate of thickness 0.8 mm. The proposed antenna has return loss values of 12.34 dB and 17.94 dB for the two resonant millimetre wave frequencies of 27.24 GHz and 28.88 GHz respectively and 12.66 dB for the satellite band frequency of 8.42 GHz. The antenna attains a peak gain of 10.2 dBi for 28 GHz millimetre wave band and 6.2 dBi for satellite X-band by exploiting an inverse micro-strip Yagi director geometry. The isolation between two ports has been found satisfactory thus making it operate efficiently forthe available Ka and X band capacity of the Wideband Global Satcom system (WGS). The experimental results regarding the fabricated prototype are presented and compared with the simulated results, which are in good agreement. The performance of proposed antenna regarding radiation efficiency, directivity, gain, radiation pattern, and good isolation between the two ports makes the antenna employed as a suitable candidate for satellite communication and especially for 5G millimetre-wave communication.....2021-06-01Radiation of Electromagnetic Waves by an Arbitrarily Oriented Slot at the End Wall of a Rectangular WaveguideMikhail Nesterenko, Viktor A. Katrich, Victor I. Kijko, and Svetlana V. Pshenichnaya A problem of electromagnetic waves radiation diffracted at a narrow rectilinear arbitrarily oriented slot cut in an end wall of a semi-infinite rectangular waveguide is solved by an asymptotic averaging method. The slot radiates into a half-space over an infinite perfectly conducting plane. An influence of slot inclination angle upon energy and spatial characteristics is numerically studied. Theoretical results are compared with experimental data. A numerical-analytical problem of a narrow rectilinear slot radiating into the space above an infinite impedance plane is also presented. The asymptotic solution for the slot magnetic current was obtained by a generalized method of induced magnetomotive forces (MMF) by using Green's functions of a space above the impedance plane. The effect of the plane with impedance coating on the slot is reduced taking into account an additional term to the slot external conductivity, for which the expressions were obtained in an analytical form.....2021-06-06MIMO Antenna Phase Error Effects on CapacityChengyi Chu and Nicholas E. Buris This paper describes the ramifications in the capacity of Multiple Input Multiple Output (MIMO) wireless links when the antenna systems involved are mischaracterized and contain phase errors. Errors in simulated as well as measured radiation patterns are considered. Also, simple deterministic Line of Sight and stochastic propagation environments are examined. The analyses are carried out on a 2×2 MIMO system. Results show that the resultant error in capacity depends on the degree of the phase error between the antenna ports, the type of propagation environment, as well as the degree of the illumination Signal to Noise Ratio (i-SNR).....PIER LettersISSN: 1937-64802021-06-07Surface-Mount PIFA Using Ball Grid Array Packaging for 5G mmWaveXi Wang, Xiubo Liu, Wei Zhang, Dongning Hao, and Yanyan Liu In this letter, a surface-mount planar inverted-F antenna (PIFA) is proposed for the 5G mmWave system using ball grid array packaging (BGA). To meet the requirement of cost-effectiveness, the proposed antenna element is designed on a single FR4 layer to achieve low cost. To achieve a compact size, the BGA packaging is used on the proposed antenna element. Finally, the size of the antenna prototype is only 4.5 mm × 4.5 mm × 1.3 mm. Besides, the surface-mount feature allows the proposed antenna to be integrated with other devices in the same system package. The simulation and measurement results are discussed in detail. The measurement results show that the impedance bandwidth of - 10 dB is 15.3 % (24.7-29.6 GHz), and the peak gain is 5.85 dBi at 28 GHz. The proposed PIFA can be used in the 5G NR bands N257 (26.5-29.5 GHz), N258 (24.25-27.5 GHz), and N261 (27.5-28.35 GHz).....
