Abstract-This paper proposes a backscattering communication technique based on modulated frequency selective surfaces (FSS) for wearable applications. The FSS is composed of dipoles loaded with varactor diodes to modulate the backscatter response, in order to separate it from the clutter. The paper describes the effect in the transponder response according to the number of dipoles, the separation between them and the effect produced when FSS is placed on-body. An analysis based on simulations of several cases and experimental results is provided.

“…Frequency selective surfaces (FSSs) are planar structures composed of a periodic array of elements that filter electromagnetic waves incident on the surface [1][2][3]. They are most well-known for their applications in stealth technology [4] and modification of radar cross section [5], but many other applications exist including the construction of radomes [6][7][8], dichroic sub-reflectors [9], lenses [10], radio frequency identification (RFID) [11], and protection from electromagnetic interference.…”

Abstract-All-dielectric frequency selective surfaces (FSSs) can serve as an alternative to their metallic counterparts when they must operate at very high power, loss must be minimized, or when the surface itself must be low observable. When metals are avoided, there is a weaker interaction with electromagnetic waves and it becomes more difficult to achieve strong suppression in the stop band while also realizing compact size, wide field-of-view or broadband operation. One attractive approach utilizes guided-mode resonance (GMR) as the filtering mechanism, but this phenomenon exhibits several drawbacks that must be overcome for practical application at radio frequencies. This paper introduces the concept of guide-mode resonance for FSSs and describes how they can be made to operate with a dramatically fewer number of periods than conventional GMR devices.

Abstract-A novel dualband frequency selective surface (FSS) with both a dielectric substrate and superstrate constructed by double-fourlegged loaded slots (DFLLSs) is investigated, in which each periodic cell consists of two neighboring DFLLSs with different dimensions, its resonant frequencies occur at 183 GHz and 220 GHz. Good selectivity performance can be easily achieved both in lower passband and higher passband by tuning the dimensions of the DFLLSs. Besides, the passbands are mainly determined by the neighboring perturb cells and can be designed independently. According to the explicit physical concept and some formulas, the design process become straightforward and simple. Its frequency performance is obtained by using numerical simulation software CST based on finite difference time domain method (FDTD). The simulated results show the good stability of the resonant frequencies and bandwidths at different polarization states and various incident angles.
