A distributed Bragg reflector (DBR) is a periodic structure formed from alternating dielectric layers that can be used to achieve nearly total reflection within a range of frequencies, with minimal losses. In this tutorial a Bragg reflector is modeled with a central wavelength of 550[nm] ... En savoir plus
This model shows how to simulate the complex discharge physics behind the well-known electrostatic discharge (ESD). The model connects the Electrical Discharge interface with the Circuit interface to simulate how ESD current is generated when a human hand touches metal. En savoir plus
Mixed-mode S-parameters describe the responses of a circuit with balanced ports excited and terminated by two types of modes: common and differential modes. They are calculated using a full S-parameter matrix of a four-port network that is composed of four single ended lines. This ... En savoir plus
Quantum dots are nano- or microscale devices created by confining free electrons in a 3D semiconducting matrix. Those tiny islands or droplets of confined “free electrons” (those with no potential energy) present many interesting electronic properties. They are of potential importance ... En savoir plus
Microstrip filters can be fabricated directly on a printed circuit board (PCB) with a microstrip line going from the input to the output. Along the microstrip line there are a number of stubs of certain lengths and widths. The design of the filter involves choosing the impedance of the ... En savoir plus
Microwave filters are used to eliminate unwanted frequency components in the output from microwave transmitters. They are typically inserted between a power amplifier and an antenna. The amplifiers are nonlinear and produce harmonics that must be eliminated with filters that have a ... En savoir plus
Wind turbines are an increasingly popular source of renewable energy. As such, the design, analysis and manufacture of wind turbines are important to the energy industry. The turbine blades are critical components of a wind turbine. When generating electric power through rotation, they ... En savoir plus
This example shows how to model a loudspeaker driver of the dynamic cone type, common for low and medium frequencies. The analysis is carried out in the frequency domain and thus represents the linear behavior of the driver. The model analysis includes the total electric impedance and ... En savoir plus
This model simulates Gaussian to Laguerre Gaussian beam shaping with the Beam Envelopes interface, the unidirectional wave formulation. The input beam is a focusing Gaussian beam with a topological spiral phase. It is known that this phase mask converts a Gaussian beam to a donut ... En savoir plus
This example simulates Trichel pulses produced by negative corona discharge under a point-to-plate configuration. The electron density and the electric field are obtained, as well as the discharge current. The discharge current clearly shows the pulsating characters. Each current pulse ... En savoir plus
