Charateristic investigation of monopole antenna on a conducting plate using method of moments;

In this paper,the radiation from a monopole on an elliptic cylinder is discussed by UTD for convex surfaces and two examples are given whose results are consistent with experimental data,which proves UTD to be available.

In the case of ground reflection, a monopole with finite diameter is studied by method of moment (MoM).

The transient scattering properties of the unloaded,uniform loaded and non-uniform loaded dipole antennas are investigated.

The paper describes the principle of measuring horizontal component of VLF electronic field by ungrounded dipole antenna in surface,and analyzes the theory and experimentation.

Based on the electromagnetic polarity character of the GPR dipole antenna,the transmitter produces an electric field with a polarization paralleled to the long axis of the antenna,the receiver is most sensitive to such kind of polarized waves.

A step-shaped broadband omnidirectional monopole antenna with dual-frequency;

Comparison of the radiated field between leaky coaxial cable and monopole antenna in the blind zone;

The SAR(Specific Absorption Rates)distribution in human head emitted by a monopole antenna handset was simulated using the finite difference time domain (FDTD) method with a three layered human head model at the frequency of 900 MHz.

The duty of the public security organs in the disposal of the natural disasters in extreme weather;

Holidays and extreme weather Power load feature extraction model

Aiming at the phenomenon of extreme weather,the paper discusses how to improve the observation ability to extreme weather when establishing the relevant operational flows and emergency response plans.
