| Simulations with Anechoic Chamber |
| Simulations with Anechoic Chamber Absorbing properties of inner covering of anechoic chamber are poor at frequencies below 30 MHz. This fact makes neglecting of walls in computational model incorrect. Construction of computational model of anechoic chamber at low frequencies and analysis of field structure is performed. |

| Modeling of Electronic Devices using Near Field Sources |
| Construction of complicated simulation model can be simplified by representation of radiating parts of the system as a closed field surfaces surrounding them. Voltage coupled from the ECU in the car represented as Near Field Source is calculated and compared with results of fullwave MoM solution. |

| Accurate Absorber Modeling |
| Anechoic chamber performance can be significantly improved if microwave absorbers with optimized characteristics will be installed over the entire inner surface of shielded room. The selection criteria for absorbers may include the attenuation levels for normal and oblique incident angles, operating frequency, bandwidth, type of bulk materials, size, shape, weight and etc. Analysis of Pyramidal absorber attenuation properties are performed using fullwave MoM three-dimensional model. |
