Progress In Electromagnetics Research

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.

Biosensing Performance of a Plasmonic-Grating-Based Nanolaser (Invited Paper)

Haoran Zhang, Jiacheng Sun, Jie Yang, Israel De Leon, Remo Proietti Zaccaria, Haoliang Qian, Hongsheng Chen, Gaofeng Wang, and Tao Wang

We introduce and numerically investigate a high-quality resonant structure formed by a dielectric low-order diffraction grating combining materials with high refractive index contrast. The proposed structure is capable of supporting multiple plasmonic modes owing to hybridization effects, modes having the characteristic of exhibiting remarkable sensing response to the change of the environment refractive index yet limited figure of merit. To improve the figure of merit, the proposed architecture is modified by adding a layer of semiconductor gain medium, as it can compensate the internal losses. The result is an active sensor showing multi-modal lasing behaviour, with very low threshold and large mode spacing. It is found that the device shows switchable response upon modification of the pump amplitude or polarization, a very important feature when it comes to sensing devices. Finally, the achieved figure of merit is 3400 RIU-1, one order of magnitude higher than the passive case and much higher than the theoretical limit for sensors based on Kretschmann configuration. Thus, the proposed architecture possesses great potentials as an optical sensor for bio-detection and environmental monitoring.....

    A Review of Metasurface-Assisted RCS Reduction Techniques

    Akila Murugesan, Krishnasamy Selvan, Ashwin Iyer, Kumar Vaibhav Srivastava, and Arokiaswami Alphones
    This review discusses the evolution of the various radar cross-section (RCS) reduction techniques, with an emphasis on metasurfaces. The paper first introduces the terms RCS and RCS reduction and then discusses conventional and modern techniques to reduce RCS. The two main strategies used are scattering and absorption. The traditional methods of shaping and Radar Absorbing Material (RAM) are first briefly reviewed, followed by an extensive review of metasurface-based RCS reduction. RCS-reducing metasurfaces have the unique characteristics of acting as scatterers and absorbers. They are also described with regard to their passive and active configurations. The RCS reduction techniques are discussed with respect to profile, bandwidth, angular stability, polarization sensitivity, design complexity, and cost-effectiveness. A comprehensive comparison chart based on the performance parameters such as bandwidth, size and angular stability is tabulated for the different types of metasurfaces. The review also details areas that require further investigation.....

    Numerical Analysis of a ITO Based Circularly Polarized Optically Transparent THz Antenna Employing Characteristic Mode Analysis

    Muhammad Asad Rahman, Md. Sarwar Uddin Chowdhury, Md. Azad Hossain, and Ahmed Toaha Mobashsher
    An optically transparent circularly polarized indium tin oxide based antenna having operability in THz region is proposed in this paper. An E-shaped slot and an I-shaped slot are embedded into an E-shaped radiating E-shaped radiating patch modeled by ITO and conductive carbon nanotube (CNT) on a polyimide substrate to obtain circular polarization. The unequal parallel slits of the E-shaped patch with an E-shaped slot lead to introduce two orthogonal modes, and hence circular polarization is achieved. Besides, integration of a I-shaped slot also helps to create the difference in magnitude of current distribution between the two working modes to get better axial ratio. Due to the high resistivity of indium tin oxide thin film, the patch of the antenna is covered with highly CNT film which improves the overall performance of the antenna. To overcome the limitations of the traditional design process, characteristic mode analysis is carried out which helps to realize and analyze circular polarization generation mechanism effectively. The proposed antenna shows a wide 3-dB axial ratio bandwidth of 9.66%. A reasonable gain of 2.61 dBic is obtained at 1.11 THz with excellent radiation performance. Wide 3-dB axial ratio bandwidth with reasonable gain makes this light weight transparent small-antenna competent for wireless and satellites applications.....

    Sierpinski-Carpet Fractal Frequency Reconfigurable Microstrip Patch Antenna Design for Ku/k /Ka Band Application

    Iqra Masroor, Jamshed Ansari, Shadman Aslam, and Abhishek Kumar Saroj
    This work discusses the effect of reconfigurability on a Sierpinski-carpet fractal microstrip patch antenna. The implementation of reconfigurability is achieved by modeling a PIN diode as a lumped RC element on HFSS (High Frequency Structure Simulator) simulation tool. The proposed antenna design is also fabricated and tested. It is highly miniaturized having a dimension of 9.5 mm × 7.4 mm and a significantly high impedance bandwidth which is desirable for most wireless communication applications. The resultant Fractal Reconfigurable Antenna (FRA) exhibits good performance parameters having frequency reconfigurability rendering it useful for Ku/K/Ka band applications.....
  • A Negative Group delay (NGD) triple passband filter with a lossy Meander Step Impedance Resonator (MSIR) is introduced in this article. The size miniaturization technique by increasing the number of meander turns is presented. In the process of filter design, the calculation of the total inductance value of the meander section is discussed in a simplified way. At the same time, the electrical and physical lengths of each section of meander resonator are calculated. The proposed filter has three passbands at 2.4, 5.0, and 7.4 GHz. The Group Delay (GD) in the three pass bands is -2.5 ns, -2.1 ns, and -2.0 ns, respectively. The more the number of meander turns is, the more the NGD will be. The proposed design is well equipped to be used in feed-forward and feed-back power amplifier applications. The frequency response exhibits satisfactory Return Losses (RLs) of -24, -25, and -22 dB at these three passbands. Four Transmission Zeros are generated at 3.35, 3.98, 6.2, and 8.31 GHz using an absorptive Folded SIR (FSIR) structure which improve the stopband performance. The overall dimension of the filter is (20.7 x 12) mm = (0.16 x 0.09)λg.....
