| 2. | The siw was analysed by the poynting ’ s theorem and eda software . the relation between the leakage of electromagnetism energy and structure size was obtained 从理论和软件仿真上充分分析基于siw结构的谐振器滤波器的基础电路。 |
| 3. | The poynting vector that represent the flow of electromagnetic power density on a sphere from a linear dipole antenna is approximated by the summation of the field of segmented line current as hertz dipoles 以赫芝偶极之电磁场合成任意长度偶极天线在球面上电磁功率密度流之时变玻因亭向量。 |
| 4. | Maxwell ' s equations conserve certain properties ? the magnetic field intensity , the electric displacement field and the poynting vector that describes the electric flux of an electromagnetic field 麦克斯韦方程中有某些特性是恒定不变的磁场强度、电位移场以及描述电磁场电通量的坡印廷矢量。 |
| 5. | This paper also analyses the affect of signal leaking using the concept of poynting , and puts forward a formula to describe the connection of antenna interval and test precision from theoretics 利用求解波印亭矢量的方法,推导了由于阵面辐射单元信号泄漏所带来的试验误差公式,进而从理论上分析了辐射单元间距对试验精度的影响。 |
| 6. | Many opo implementations are limited by problems with conventional birefiingent phase - matched techniques in available materials , such as poynting - vector walk - off , low effective nonlinear coefficient , and inconvenient phase - matching temperature and angles 常规双折射位相匹配技术的opo有许多缺点,比如光束走离效应、非线性转换效率较低、位相匹配温度及匹配角的限制,阻碍了opo的发展。 |
