• Unstable resonators
• Edge wave
• Uniform asymptotic
• Lowest-loss mode

In this paper, the formula of the edge wave (EW) which is applicable for strip negative branch unstable resonators is derived. It is shown that the lowest-loss mode can be represented as the superposition of these EWs in an explicit form, the validity is verified by numerical comparison with the classic power method.
