abstract = {<p style="text-align: justify;">This paper is concerned with the Cauchy problem for the modified Helmholtz equation in an infinite strip domain $0 &lt;x\le 1$, $y\in R$. The Cauchy data at $x=0$ is given and the solution is then sought for the interval $0&lt; x\le 1$. This problem is highly ill-posed and the solution (if it exists) does not depend continuously on the given data. In this paper, we propose a fourth-order modified method to solve the Cauchy problem. Convergence estimates are presented under the suitable choices of regularization parameters and the a priori assumption on the bounds of the exact solution. Numerical implementation is considered and the numerical examples show that our proposed method is effective and stable.</p>},
