“…As shown in Figure 5(a), each FSS has two resonant frequencies (the first one and the second one), which more or less shift to the higher frequency at the incident angle of 60 • . It is obviously that the frequency deviation of the proposed FSS is less than that of the FSS in [10]. The further simulated results of the resonant frequency deviations in various incident angles are provided in Figure 5(b), where Δa 1 and Δb 1 represents the first resonant frequency deviation of the proposed FSS and the FSS in [10] while Δa 2 and Δb 2 corresponds to the second resonant frequency.…”

“…The main difference between the proposed FSS and the FSS in [10] is the parasitic patches. In order to illustrate the function of parasitic patches that can reduce the resonant frequency deviation at wide incident angle, the simulated reflection coefficients of the proposed FSS and the FSS in [10] are presented in Figure 5(a).…”

“…Compared with single-layer structure, a multi-layer FSS which has a smaller inter-element spacing was proposed in [10] to provide an UWB bandwidth with the incident angle in the range from 0 • to 30 • . The structure in [11] utilized the curved slot element to reduce the inter-element spacing, hence its wideband response was capable of remaining stable as the incident angle increases from 0 • to 40 • .…”

“…Its −3 dB bandwidth attains 8.64 GHz (3.49-12.13 GHz), which covers the C and X bands, and the fractional bandwidth exceeds 110%. Compared with the UWB FSS in [10], the proposed FSS appends some parasitic patches to enhance the capacitive and inductive effects, then provides the more stable performance at incident angle of 60 • for both TE and TM polarizations. The unit cell of the proposed FSS is 0.09λ 0 × 0.09λ 0 , where λ 0 corresponds to free space wavelength at the lower cut-off frequency, and the overall thickness is 4 mm.…”

Abstract-An ultra-wideband frequency selective surface (FSS) for wide incident angles is proposed. Its −3 dB bandwidth is from 3.49 GHz to 12.13 GHz, and the fractional bandwidth exceeds 110%. Some parasitic patches are appended to reduce the deviation of resonant frequency under wide-angle incidence. The proposed FSS exhibits an improved stability when the incident angles are in the range from 0 • to 60 • . The relative simulated and measured results are provided to validate its effectiveness.

The development of in-vivo communications and networking systems has the potential for improving the healthcare delivery while also enabling the creation of new services and applications. In-vivo communications provide wireless networked cyber-physical systems of the embedded devices that enable accurate, quick, and cost-effective responses under a variety of circumstances. Also, it is focused upon modeling and characterizing in-vivo wireless channel, as well as contrasting it to other well-known channels. In this paper, channel coding is also mentioned because it improves data rates and performance gain. This work also discusses present problems and potential research topics for in-vivo communications. This article aims to show the researchers how the orthogonal frequency multiple access (OFDMA) technique improved the performance of in-vivo channel and how it is outperformed compared to the other techniques (TDM, TDMA, CDMA and OFDM) also how the OFDMA outperformed equalizers and channel coding in terms of bit error rate with giving a significant improvement of data transmitting and avoiding inter symbol interference. However, when it comes to the in-vivo communications, the modeling of in-vivo wireless channel is vital.Understanding the features of the in-vivo channel is critical for achieving optimal processing and designing successful procedures that allow WBANs to be arranged inside the human body.

In this work, a broadband frequency selective surface (FSS), which is insensitive to incident angle is designed. This FSS is composed of three metallic layers and two identical dielectric layers. The top and bottom layers are two identical metal patches, while the middle layer is a slot structure etched in a metal screen. This FSS achieves a broadband pass‐band response from 9.8 to 20.8 GHz by combining different resonant modes at 12.6, 15.2, and 19.2 GHz, respectively. Meanwhile, this FSS can still function properly at up to 60° oblique incidence for TE polarization, which is attributed to the independence of incident angle of the middle slot layer and miniaturization of the whole structure. In addition, two key parameters (that are of great importance in adjusting flatness of the pass‐band) of the FSS element have been studied. A prototype of the FSS was manufactured and measured. Good agreements between measurements and simulations are observed.
