E2M (Engineer with EM waves)

Features of E2M (Engineer with EM waves)

- The simulator adopted a fast and advanced 1D EM solver

- E2M can simulate 1D stacked (layered) structures to extract reflectance, transmittance, and absorptance as functions of incident angle and thickness with a mixed polarization ratio.

- E2M can simulate 1D stacked structures to extract photonic band structures for TE and TM modes.

- The current version of E2M supports LHI (linear, homogeneous, and isotropic) medium.

- User-defined material can be constructed within this simulator.

- The material database at refractiveindex.info was internally adopted to offer a prompt solution with practical material parameters. However, nonmagnetic material is assumed when converting the complex refractive index of the database into complex permittivity and complex permeability.

- Extracted raw data and figures can be exported through email or the Files app from Apple easily.

- Various simulation domain parameters can be selected in “Setting/Etc” tab-view: frequency domain, wavelength domain, or energy domain with electron-volts.

- Freeware mode is offered, which allows to simulate less than four layers, but infinite repetition of the designed layers within three layers is possible. Therefore, several cases for the academic calculations are possible without subscription.

In-app Subscriptions at E2M

E2M offers “One month”, “One year” and “Lifetime” subscription options. The period of the subscription is exactly identical to the subscription name itself. The subscription purchase removes the maximum three layers design limitation during the service period. “One month” and “One year” subscriptions will automatically renew if you do not cancel. You can cancel the subscription at any time in your “Subscriptions” section of your “Apple Account”.
