“…[6], the coefficient of concentration of energy is calculated. It usually decreases with increasing intensity because of nonlinear decay of the wave (see the review by Naugol'nykh [7]). However, nonlinearity is sometimes able to increase the concentration due to the sharper focusing of higher harmonics [8,9].…”

Brand-new equations which can be regarded as modifications of Khokhlov-ZabolotskayaKuznetsov or Ostrovsky-Vakhnenko equations are suggested. These equations are quite general in that they describe the nonlinear wave dynamics in media with modular nonlinearity. Such media exist among composites, meta-materials, inhomogeneous and multiphase systems. These new models are interesting because of two reasons: (1) the equations admit exact analytic solutions and (2)
