Recently, a technique for fast and accurate phase analysis called sampling moiré method has been developed for measurement of small-displacement distribution. In this study, a distribution of phase error caused by linear interpolation in case with mismatch between the sampling pitch and the grating pitch is theoretically analyzed. Moreover, a technique for effective phase compensation is proposed to reduce the periodic phase error. The performance of our compensation method is validated by a computer simulation. Phase analysis can be performed more accurately even in the case that the sampling pitch does not match to the grating pitch strictly.

В данной работе представлены результаты разработки СВЧ монолитной интегральной схемы шестиразрядного фазовращателя и усилителя мощности диапазона частот 26-30 ГГц. СКО ошибки по фазе и амплитуде фазовращателя составили 1,2 град. и 0,13 дБ соответственно. Максимальная выходная мощность и КПД по добавленной мощности усилителя в точке сжатия Ку на 1 дБ составили 30 дБм и 20 % соответственно. This paper describes the design, layout, and performance of 6-bit phase shifter and power amplifier monolithic microwave integrated circuit (MMIC), 26-30 GHz band. Phase shifter MMIC has RMS phase error of 1.2 deg. And RMD amplitude error is 0.13 dB. MMIC power amplifier has output power capability of 30 dBm at 1 dB gain compression (P-1dB) and PAE of 20 %.

In this paper, effective electromagnetic (EM) focusing achieved with a phase compensation technique for microwave hyperthermia systems is proposed. To treat tumor cells positioned deep inside a human female breast, EM energy must be properly focused on the target area. A circular antenna array for microwave hyperthermia allows EM energy to concentrate on a specific target inside the breast tumor. Depending on the cancerous cell conditions in the breast, the input phases of each antenna are calculated for single and multiple tumor cell locations. In the case of multifocal breast cancer, sub-array beam focusing via the phase compensation technique is presented to enhance the ability of EM energy to concentrate on multiple targets while minimizing damage to normal cells. To demonstrate the thermal treatment effects on single and multiple tumor locations, the accumulation of the specific absorption rate (SAR) parameter and temperature changes were verified using both simulated and experimental results.
