“…Usually, a series of excellent properties will be induced when the plasmonic Fano resonance is generated such as large local field enhancement, high sensitivity to surrounding environment or structural parameters, large absorption or transmission of light at resonance frequency, etc. Benefiting from these characteristics, Fano resonance has been widely used in various fields including surface enhanced spectroscopy [20,21], Fano switch [22], Fano interferometer [23], ultrasensitive biosensor [24,25] and so on. A crisscross dimer nanostructure has been proposed by Zhang et al, in which a tunable Fano resonance can be generated.…”

Various noble metal nanostructures based on surface plasmon have been proposed in recent years. Under the irradiation of incident light, if the oscillation frequency of the electrons on the metal surface matches the frequency of the incident light wave, resonance will occur. In the resonance state, a special electromagnetic mode is formed: the electromagnetic field is localized and enhanced in a small area of the structure surface. In our artic, a fish-like dimer (F-LD) nanostructure has been proposed. The dark second order magnetic mode is excited due to the near-field coupling between two parts of the dimer. An asymmetry Fano linetype will be generated when the dark magnetic mode is coupled with the bright electric mode. Rotating the structure, the fourth and sixth order magnetic modes can be generated. When the radii of the semi-rings in the gap are changed, the first and third order magnetic modes can be observed. More interestingly, as the number of semi-ring in the gap increasing, the spectral line shape can be controlled and higher-order magnetic modes can be generated regularly. At the same time, multiple Fano resonances can be observed in the extinction spectrum and the spectrum can be modulated simultaneously in multiple bands. By changing the structure parameters, the first, second, third, fourth, sixth and eighth order magnetic modes can be obtained. In different cases, the magnetic field can be enhanced greatly in different areas of the gap, and the maximum magnetic field enhancement reaches 49 times of the incident field. For these characteristics, our structure can be well used in multi-band sensing and surface enhanced spectroscopy.

“…Several research works in the direction of designing antenna for medical implants have been carried out in the ISM band for biometry. Recently, MICS has specified 402-405 MHz for this purpose to minimize interference with other services (Aleef et al, 2017;Herth et al, 2017;Asili et al, 2012;Jung, 2016;Huang et al, 2013;Scarpello, 2011;Emami-Nejad and Mir, 2017;Yilmaz et al, 2008;Yang et al, 2016;Bahrami et al, 2015). This means that the wavelength is nearly 74 cm, which has a direct relation with the antenna dimensions.…”

Purpose The paper aims to focus on implantable antenna sensors used for biomedical applications. Communication in implantable medical devices (IMDs) is beneficial for continuous monitoring of health. The ability to communicate with exterior equipment is an important aspect of IMD. Thus, the design of an implantable antenna for integration into IMD is important. Design/methodology/approach In this review, recent developments in IMDs, three types of antenna sensors, which are recommended by researchers for biomedical implants are considered. In this review, design requirements, different types of their antenna, parameters and characteristics in medical implants communication system (MICS) and industrial, scientific and medical (ISM) bands are summarized here. Also, overall current progress in development of implantable antenna sensor, its challenges and the importance of human body characteristics are described. Findings This article give information about the requirements of implantable antenna sensor designs, types of antennas useful to design implantable devices and their characteristics in MICS and ISM bands. Recent advancement in implantable devices has led to an improvement in human health. Originality/value The paper provides useful information on implantable antennas design for biomedical application. The designing of such antennas needs to meet requirements such as compact size, patients’ safety, communication ability and biocompatibility.
