Fresnel Coefficients

Compute indoor propagation using Fresnel coefficients.

Model type

The propagation project is for an indoor scenario for a single-story building. The simulation is done for only a single prediction height at 1.5 m above the ground.

Sites and Antennas

There is only one omnidirectional transmitter, situated at a height of 2 m and operating at 2 GHz.
Tip: Click Project > Edit Project Parameter and click the Sites tab to view the transmitter details.

Computational Method

This project uses standard ray tracing without a preprocessed database.
Tip: Click Project > Edit Project Parameter and click the Computation tab to change the model.
In this part of the example, the simulation uses Fresnel equations for the determination of the reflection and transmission loss and the GTD/UTD (geometrical theory of diffraction / uniform theory of diffraction) for the determination of the diffraction loss The model uses four physical material parameters:
  1. thickness
  2. permittivity
  3. permeability
  4. conductivity


Propagation results show, at every location, the power received from the transmitting antenna. The results are shown for a prediction plane at a height of 1.5 m from the floor.
