Investigation on Transient Response of Linear Dipole Antennas in the Presence of HEMP Based on Equivalent Circuit
Interfering electromagnetic energy could be a very powerful pulse which is generated and incident onto communication system such as linear wire antenna through direct radiation. In this paper, the transient responses of ...
A New Closed-Form Expression for Dispersion Characteristics of Fundamental Mode of SIW by Least Squares Method
A new and accurate closed-form expression is introduced using least squares method (LSM) to

Side Lobe Level Reduction of Any Type of Linear Equally Spaced Array Using the Method of Convolution
In most applications of antenna arrays, side lobe levels (SLLs) are commonly unwanted.
Especially, the first side lobe level which determines maximum SLL is the main source of electromagnetic
interference ...
