In this article, the electromagnetic (or RF) behavior of the azimuthally partitioned axially periodic metal diskloaded coaxial structure was investigated using an equivalent circuit approach in the presence of the electron beam. In the analysis, the linearized Maxwell's fluid equation (also known as Vlasov-Maxwell's equation) was used to analyze the region in which the electron beam was present. The expression for the equivalent series inductance and shunt capacitance per unit length for the equivalent transmission line was derived in the electron beam present and absent case. The derived expressions include all the harmonics effects present inside the structure. Furthermore, the expression of the dispersion relation and temporal growth rate (TGR) was derived using the calculated equivalent series inductance and equivalent shunt capacitance. The output RF power and energy were also calculated analytically and validated through the PIC simulation. The results were compared with the already reported literature, and the relative error between them was below 5%. In addition, the effect of different beam parameters on the TGR behavior was also analyzed. Index Terms-High-power microwave (HPM), magnetically insulated line oscillator (MILO), slow-wave structure, temporal growth rate (TGR). I. INTRODUCTIONI N RECENT few years, it is noticed that the research activity in the high-power microwave (HPM) sources, which is capable to generate multifrequency, is drastically increased because of its potential application in the fields of defense application, linear particle accelerator, and plasma heating [1]. Various HPM sources, such as magnetically insulated line oscillator (MILO), transit-time oscillator (TTO), and relativistic backward-wave oscillator (RBWO), have been developed to generate bifrequency RF signals [2]-[4].

“…[13][14][15][16] Today, the IPD process with high-density wiring has been established for commercial use and many integrated passive devices other than new CMFs have been developed. [17][18][19][20][21][22][23][24][25] Since metal wiring layers of those are less than three layers, the integration in the vertical direction is insufficient, and the wiring tends to spread horizontally. Therefore, the external dimensions of CMF-IPDs are not small enough, and it is almost equivalent to an external component.…”

The new differential signal balancer embedded in the metal wiring layer of silicon LSI having increased wiring density and improved characteristics is developed. An internal delay line circuit is stacked vertically to obtain a larger delay time than the extended horizontally structure, and the two inductors for common-mode noise rejection are configured with a stacked bifilar winding structure to obtain higher effective coupling and lower parasitic resistance. Compared to the previous design, the common-mode rejection ratios (CMRR) at 2.4 GHz and 5.4 GHz have been improved by 4.0 dB and 4.6 dB in a smaller area of 120 × 230 μm2, respectively.
