An exponential shape function for wormholes in modified gravity

Abstract

Here, we propose a new exponential shape function in wormhole geometry within modified gravity. The energy conditions and equation of state parameter are obtained. The radial and tangential null energy conditions are validated, as well as the weak energy condition, which indicates the absence of exotic matter due to modified gravity allied with such a new proposal.
