Our paper "Spheroidal Molecular Communication via Diffusion: Signaling Between Homogeneous Cell Aggregates" (arXiv link) has been accepted to appear in IEEE Transactions on Molecular, Biological, and Multi-Scale Communications. We model two spheroids as transmitter and receiver in a diffusion-based molecular communication system. Both spheroids are modeled as spheres whose porous features are approximated with a lower diffusion coefficient than that of the surrounding fluid medium. We derive the end-to-end channel impulse response and characterize the corresponding communications performance.

This paper is an output of the SIMBA project and is the first journal paper of Mitra Rezaei's PhD. It was also co-authored with Hamidreza Arjmandi from our group, in addition to Mohamad Zoofaghari (Yazd University, Iran) and our SIMBA project collaborators at AstraZeneca Sweden (Kajsa Kanebratt, Liisa Vilen, David Janzen, and Peter Gennemark).
