“…12 and 13 for T e = 300 K and T e = 100 mK respectively. In both plots we assume the driving frequency ω d is tuned to couple the center-of-mass motion to the S 121 acoustic mode as described in the main text, and take typical values for YIG, namely [106] r = 4.4 and µ(ω d ) = 1 + i0.005. The latter is consistent with drivings far away from the magnon resonance [107,108], which is a good assumption because ω d = ω m − ω tx + g/χ 0 ≈ ω m + 100g.…”

“…( 41), for various reasons. First, at low frequencies, the dielectric loss of YIG usually takes on larger values than the one for silica [106]. Second, the average field experienced by the micromagnet is in general much smaller than B (4) max , because, on the one hand, the motional amplitude of the center of mass is significantly reduced when it is cooled, that is X2 .…”

Recently [1], we proposed a new way to engineer a flexible acoustomechanical coupling between the center-of-mass motion of an isolated micromagnet and one of its internal acoustic phonons by using a magnon as a passive mediator. In our approach, the coupling is enabled by the strong magnetoelastic interaction between magnons and acoustic phonons which originates from the small particle size. Here, we substantially extend our previous work. First, we provide the full theory of the quantum acoustomagnonic interaction in small micromagnets and analytically calculate the magnon-phonon coupling rates. Second, we fully derive the acoustomechanical Hamiltonian presented in Ref. [1]. Finally, we extend our previous results for the fundamental acoustic mode to higher order modes. Specifically, we show the cooling of the center-of-mass motion with a range of internal acoustic modes. Additionally, we derive the power spectral densities of the center-of-mass motion which allow to probe the same acoustic modes. arXiv:1912.08745v2 [cond-mat.mes-hall]

“…That is the reason behind many researchers are working to design their antennas considering the MPA technique and using different materials as well as different methods and designs to gain optimum parameters, which are required for their applications. New technologies such as using screen printing of conductive paint and using sticky copper film [5]- [7] as well as finding new designs that can affect the gain and the bandwidth of the MPA [8]. The complicated relationships between different parameters of MPA make the control on MPA parameters very sophisticated and it is very hard to get high gain and wideband at the same time [9].…”

In this paper, an end-fire microstrip patch antenna (MPA) is proposed of 3 GHz as a center frequency, designed, simulated, and measured to work on WiMAX frequencies within standard of 802.16e (WiMAX). A high gain ranged between (12.117-13.324) dB, high front to back ratio (F/B) of (35.770) at the center frequency, a wide band of 1.701 GHz, low profile, and semi-ideal voltage standing wave ratio (VSWR) of 1.053 is achieved. The simulation is done using computer simulation technology (CST-MW). The proposed design is based on two Fire-retardant substrates (FR-4) of relative permittivity (ε) 4.3+j0.025 and 1.53 mm thickness for each one, which is considered a high loss material. The measurement results show good agreement with the simulated results. In addition, the design can be used for harvesting power supply from mobile towers. Finally, the proposed design is compared with two other designs in terms of power conversion efficiency and overall size.

An experimental study of microstrip patch antenna designed and fabricated on FR4 epoxy substrate is presented. Further a performance comparison of designed antenna is made with proposed design using Gallium doped Ba-Sr hexagonal ferrite substrate. Microstrip feed line is used for inputting the signal to antenna. The whole simulation is done on HFSS simulator (version 13.0).The center frequency for proposed antenna is 10GHz and is optimized for significant performance parameters viz return loss, bandwidth, VSWR and gain. It was observed that the designed antenna provides better results with ferrite substrate as compared to FR4 epoxy substrate showing -10db broad bandwidth of 4.2GHz in the frequency region 8.2GHz to 12.4GHz. Although, the results of other parameters like return loss, VSWR and gain are found to be optimum with FR4 substrate as compared to mentioned ferrite substrate. The prototype of proposed antenna with FR4 epoxy substrate is fabricated and tested to attain the experimental results. The measured results are found to be better than simulated results. Thus the proposed antenna structure can be considered suitable for microwave communication application in X-band.
