## Contribution

It introduces a novel analysis of wave transmission in a lattice of beams with rotational inertia, highlighting unique high-frequency features in Rayleigh beams.

## Key findings

- High-frequency transmission features in Rayleigh beams
- Differences between Euler-Bernoulli and Rayleigh beams at elevated frequencies
- Enhanced understanding of dynamic response in beam networks

## Abstract

The paper presents a novel analysis of a transmission problem for a network of flexural beams incorporating conventional Euler-Bernoulli beams as well as Rayleigh beams with the enhanced rotational inertia. Although, in the low-frequency regime, these beams have a similar dynamic response, we have demonstrated novel features which occur in the transmission at higher frequencies across the layer of the Rayleigh beams.
