EasyKeyHub represents the next step in the evolution of physical security. By bridging the gap between traditional locks and modern digital management, it provides a reliable, scalable, and user-friendly way to protect what matters most. In a world where "easy" and "secure" are often at odds, this platform proves that you can have both. AI responses may include mistakes. Learn more

Whether you are managing ten keys or ten thousand, the system is built to scale with your organization's growth. Ideal Use Cases

Secure sensitive areas like server rooms and executive suites while allowing general access to common areas.

At its core, EasyKeyHub is an integrated platform that combines secure storage with intelligent software. It is designed to simplify the lifecycle of key management—from issuance and tracking to return and auditing. By digitizing the "paper-and-clipboard" method of key tracking, it provides real-time visibility into who has access to which assets at any given moment. Key Features and Capabilities

Easily manage access for maintenance crews, real estate agents, and new tenants.

OptiFDTD enables you to design, analyze and test modern passive and nonlinear photonic components for wave propagation, scattering, reflection, diffraction, polarization and nonlinear phenomena. The core program of OptiFDTD is based on the Finite-Difference Time-Domain (FDTD) algorithm with second-order numerical accuracy and the most advanced boundary conditions – Uniaxial Perfectly Matched Layer (UPML).

The algorithm solves both electric and magnetic fields in temporal and spatial domain using the full-vector differential form of Maxwell’s coupled curl equations. This allows for arbitrary model geometries and places no restriction on the material properties of the devices.

Applications

  • Surface Plasmon Resonance (SPR)
  • Photonic band gap materials and devices
  • Nano-particles, and tissue cells
  • Diffractive micro-optics elements and lenses
  • Complex integrated optics structures
  • Nonlinear materials, dispersive materials
  • Optical micro-ring filters and resonators
  • Grating based waveguide structures
  • Electromagnetic phenomena

 

Interface with Popular DesignTools
  • Code V
  • Zemax
