Lumped Element Multimode Modeling of Balanced-armature Receiver with COMSOL Multiphysics® Software

Wei Sun [1],
[1] Institute of Acoustics, Tongji University, China

For the lack of higher order modes, lumped element (LE) models currently used may be insufficient to predict the system of balanced-armature receiver (BAR). We develop a LE multimode model for BAR in the frequency domain based on the techniques of mode decomposition, truncation, and ... En savoir plus

[1] Beijing Institute of Technology, School of Physics, Beijing, China
[2] Science and Technology on Electromagnetic Scattering Laboratory, Beijing, China

Recently, the researchers usually use the hydrodynamic Drude model (HDM)to investigate the nonlocal optical response of metallic nanostructure. The advantage of the HDM is easy to implement numerical calculation for larger and more complex shaped nanoplasmonic structures. For the HDM, it ... En savoir plus

Low Temperature Microwave Treatment of Sphere Materials

Huangcheng Zhu [1], Youqi Deng [1], Qian Meng [1], Quansheng Wang [1]
[1] Sichuan University, Chengdu, China

Microwave heating has many advantages over the traditional heating method, such as needing shorter time, saving more energy, and being easier to control. But there still are some problems.(1) Themal runaway still exists because the reflection and absorption of microwave by the reactants ... En savoir plus

The Metal Patch Effect on the Microwave Heating Uniformity

Huacheng Zhu [1], Qian Meng [2], Quansheng Wang [2], Youqi Deng [2],
[1] Institute of Applied Electromagnetics, Sichuan University, Chengdu, China
[2] College of Physical Science and Technology, Sichuan University, Chengdu, China

Microwave heating is known for its efficiency and instantaneity. However, the non-uniformity of the microwave heating has limited the development of its application in industry. In order to solve this problem, a metal patch sticking to the turntable was proposed. During the heating ... En savoir plus
