Metamaterial simulation software

What are Metamaterials?

Metamaterials are structured to control and manipulate the electromagnetic properties of the material. This manipulation allows guidance and control of electromagnetic propagation into, through and out of the material.

This manipulation is achieved by the material’s structure and properties, and can be either fixed or dynamic/ controllable.

What are Intelligent Reflective Surfaces (IRS/ RIS)

A metamaterial containing an array of elements sized less than the wavelength of the radiation of interest, will interact with and manipulate the radiation in a ways not often achievable by conventional antennas and materials. Such devices may be composed of small patches, antennas, inductors, switches, diodes, LRC circuits, etc. One application of such devices is the control and manipulation of how the incident radiation is received and transmitted or reflected into the surrounding environment.

How do we simulate them in a system

IRS are simulated in EMSlice as an array of patch antennas of a size and spacing less than the wavelength of the radiation of interest. The electromagnetic properties of each component of the array can be set specifically to suit the scenario. Each element can then be simulated as a reflector/ scatterer, etc. The array can be designed and included into a wireless networking simulation or similar.
