E2M (Engineer with EM waves) vs Emergency Action Plan

Engineer with EM waves (E2M) is a powerful and fast 1D electromagnetic solver designed for engineers, researchers, and students. Analyze complex layered structures, extract photonic bands, and simulate optical properties directly on your iOS device. Key Features: - Advanced 1D EM Solver: Simulate 1D stacked (layered) structures with high-speed performance. - Comprehensive Analysis: Calculate Reflectance, Transmittance, and Absorptance (RTA) as functions of incident angle, thickness, and frequency. - Polarization Control: Analyze arbitrary polarization states. Define complex TE and TM inputs to simulate Linear, Circular, or Elliptical polarization interactions. - Photonic Band Structures: Extract band structures for both TE and TM modes to analyze periodic systems. - Material Library: 1. Built-in integration with the refractiveindex.info database for immediate access to practical material parameters (converts complex refractive index to complex permittivity/permeability assuming non-magnetic media). 2. User-Defined Materials: Create custom materials, including general LHI (Linear, Homogeneous, Isotropic) and Metamaterials (Double Negative/DNG). - Flexible Domain Settings: Switch simulation parameters between Frequency (THz), Wavelength (μm), or Energy (eV). - Data Export: Easily export raw data (.csv) and figures via Email or the iOS Files app for post-processing. Freeware Mode: E2M offers a generous free mode allowing designs of up to 3 layers. It supports infinite periodic repetition of these layers, enabling a wide range of academic calculations and case studies without a subscription. In-App Subscriptions: Unlock the full potential of E2M to design structures with unlimited layers. - Options: One Month, One Year, Lifetime. - Benefit: Removes the 3-layer limitation during the subscription period. - Terms: Subscriptions (excluding Lifetime) automatically renew unless canceled at least 24 hours before the end of the current period. You can manage or cancel your subscription anytime in your Apple Account settings.
