“…According to the material and structural characteristics, the bandgap performance of metamaterial structures can be generally classified into fixed bandgap characteristics and tunable bandgap characteristics [17]. Fixed bandgap metamaterial structures have been studied for many years [18][19][20][21][22]. The materials and structures required are some common ones, such as beam-plate composite metamaterial structures [23] and rod-beam composite metamaterial structures [24].…”

As an important tool for monitoring the marine environment, safeguarding maritime rights and interests and building a smart ocean, underwater equipment has developed rapidly in recent years. Due to the problems of seawater corrosion, excessive deep-sea static pressure and noise interference in the marine environment and economy, the applicability of manufacturing materials must be considered at the beginning of the design of underwater equipment. Piezoelectric metamaterial is widely used in underwater equipment instead of traditional materials because the traditional materials can not meet the application requirements. In this paper, according to the application range of piezoelectric metamaterials in underwater equipment, the current application of piezoelectric metamaterials is reviewed from the aspects of sound insulation and energy conversion. On this basis, the future development prospect of piezoelectric metamaterials in underwater equipment is introduced.

“…Most of these band-pass filters based on AFSIWs and designed using different strategies, show narrow-band characteristics, having a fractional bandwidth around 3%. There are a few filter designs with higher FBWs, like an AFSIW design in [21], where FBW = 15%, or the AFSIW bandpass filters presented in [20], [26] which present similar FBWs, but exhibit a poorer rejection band. Only an ESIW design, presented in [25], achieved an extremely large FBW of 31.5%, although the passband was too close to the ESIW cut-off frequency, and a poor matching was obtained in the lower passband edge, thus reducing substantially such value in practice.…”

The electrical response of low-frequency band-pass filters based on periodic substrate integrated waveguide (SIW) technology typically shows permitted and forbidden frequency bands. Therefore, this type of filters can be designed using a conceptually very simple and efficient procedure based exclusively on the study of the dispersion properties of the periodic structure. In this paper, we go a step further with the design of a periodically air-filled SIW band-pass filter in which part of the dielectric substrate is removed to reduce insertion losses, and whose unit cell parameters, which are directly related to the center frequency (f c ) and bandwidth (BW) of the first passband, and also to the first stopband or bandgap (BG) of the structure, have been appropriately selected for filtering purposes, thus providing some useful design rules. Furthermore, we apply the concept of glide symmetry for achieving a much larger fractional bandwidth (FBW) than that obtained in conventional air-filled SIW filters found in the technical literature. Finite implementations of both periodic structures with and without glide symmetry have been analyzed, showing their filtering response for validation purposes. Additionally, to overcome the matching level restrictions in the resulting air-filled periodic SIWs, a microstrip-to-SIW transition including a novel coupling iris is proposed. A prototype of the proposed air-filled glide-symmetric periodic SIW filter has been manufactured and experimentally validated, illustrating the potential of this technique to obtain large FBWs that can not be achieved in conventional air-filled SIW filters. The proposed filter proves to be a good candidate for millimeter wave applications. INDEX TERMSBand-pass filters, substrate integrated waveguide (SIW), glide symmetry, microstrip transition. Recently, several modified SIWs have been proposed in which the dielectric substrate has been partially or fully removed to improve the quality factor [13]-[18], due to the reduction of the dielectric losses. Different implementations of such modified SIWs can be found in the technical literature, known as modified SIW (MSIW) [13], hollow SIW (HSIW) [14], air-filled SIW (AFSIW) [15], [19], dielectricless SIW (DSIW) [17] and empty SIW (ESIW) [18]. Such modified SIWs have been successfully used to implement
