“…With the introduction of the OFDM, SC-FDE and MIMO-OFDM, the communication rate has been greatly improved. 3 Characteristic of the Acoustic-Electric Channel A common system for ultrasonic wireless communication through metal barriers has a sandwiched multi-layer composite structure, in which piezoelectric transducers are closely stuck at opposite positions, normal to both sides of a metal barrier [6,7,[12][13][14][15][16][17][18]26,. As shown in Fig.…”

Ultrasound can be used as a carrier to realize wireless communication to and from a metal-enclosed space, which has the characteristics such as immunity to the electromagnetic shielding effect and non-destructive penetration of metal obstacles. This paper firstly reviews the previous studies in the field of ultrasonic wireless communication through metal barriers, and summarizes their achievements and the existing problems. Secondly, an overview of the research methods involved in studying the characteristic of acoustic-electric channel is presented, and the principles are introduced for the actual measurement method, equivalent circuit method, ABCD parameter method, finite element analysis method and time-domain finite difference method. Then, an overview of the communication algorithms are presented such as orthogonal frequency division multiplexing (OFDM), single-carrier frequency domain equalization and multiple input multiple output OFDM. Finally, the potential future study are proposed in light of the trend of development and unsolved problems.

“…Moss et al [6,7] have presented an equivalent circuit model of the sandwiched plate and developed an "acoustic-electric feed-thru" to transmit both power and data through the aluminum skin of aircraft using ultrasound. Wilt et al [8][9][10] have also investigated finite element modeling for a two-transducer through-wall ultrasonic communication system and proposed one-dimensional pressure transfer models for the acoustic-electric transmission channels. Yang et al [11] recently have modeled the acoustic-electric channel and analyzed the effect of load on transmission efficiency.…”

Wireless ultrasonic vibration energy transmission systems through metal barriers based on piezoelectric transducers have drawn a lot of focus due to the advantage of nonpenetration of the barriers, thus maintaining the integrity of sealed structures. It is meaningful to investigate appropriate modeling methods and to characterize such wireless ultrasonic energy transmission channels with different geometric shapes. In this paper, equivalent circuit modeling and finite element modeling methods are applied to the planar metal barrier channel, and a 3-dimensional finite element modeling method is applied to the cylindrical metallic barrier channel. Meanwhile, the experimental setup is established and measurements are carried out to validate the effectiveness of the corresponding modeling methods. The results show that Leach's equivalent circuit modeling method and finite element modeling method are nearly similarly effective in characterizing the planar metal barrier channel. But for a cylindrical metal barrier, only the three-dimensional finite element modeling method is effective. Furthermore, we found that, for the planar barrier, the effect of standing waves on the efficiency of wireless energy transmission is dominated. But for the curved barrier, only the resonant phenomenon of the piezoelectric transducer exists.

To demonstrate it firstly we replace equation (75) in the expression of the speed of sound of the piezoelectric transducer and apply the first order Taylor series expansion (84) Considering the change in the speed of sound, then β which is defined in (21) receives a complex term and is written as (85) The propagation constant was modeled with the attenuation coefficient equals to zero. However, implying the separated losses in the model transforms ϒ as follows (86) The effect of the losses in the constant Z, defined in Eq.…”
